Bind PyMEOS to the MEOS master surface

PyMEOS 1.4.0a1 requires pymeos-cffi 1.4.0a1 or later and calls MEOS master's
names and signatures. Text, timestamp, date and interval input and output go
through cstring_to_text, text_to_cstring, timestamptz_in, date_in and
interval_in; multiplication through the mul_* family; the conversions to an
instant, sequence or sequence set through temporal_as_; the temporal
distance of numbers through the tdistance_ family, which takes an int for a
TInt and a float for a TFloat; and the box nearest approach distance of a
temporal point through nad_tgeo_stbox.

The spatial relationships drop their restr and atvalue arguments, and the
distance, length, speed and nearest approach functions take spheroid=True,
the MobilityDB default. The tiling and split functions pass
border_inc=True, the MobilityDB default, so a value on the upper border
lands in the tile that starts there and time_split_n answers an (n+1)th
tile holding the end value when the end is inclusive. Set and span set
accessors read the array from the (array, count) pair the functions return,
and the time distances convert the returned interval to a timedelta.

Build the all-families MEOS and its catalog in the test workflow

The PyMEOS-CFFI cdef covers every optional MEOS family and is projected from
the MEOS-API catalog, so the test workflow derives the catalog once with the
shared provision-meos action, from the MobilityDB branch the package version
maps to, and each test job builds libmeos with every family: through
provision-meos on Linux and with -DALL=ON on macOS. PyMEOS-CFFI's header is
projected from that catalog and the installed library before it is built.

Align the test expectations with MEOS master

MF-JSON writes the full ISO 8601 offset (+00:00) and states the CRS of a
geography; the temporal hash values are those temporal_hash answers; the
split tests expect the tile that holds a value on the upper border; and the
min and max restrictions, which MobilityDB defines for tint, tbigint, tfloat
and ttext, raise for tbool and the temporal points.

The adjacent instant of the tint topological test takes the value 2 at the
same timestamp: two instants at different timestamps are apart in time, so
their boxes are not adjacent.

Test the space tiles and the value-time tiles

STBox.tile of a trip's box answers the 5 km space tiles of the trip, with
their space dimension, and TGeomPoint.tile answers the trip's pieces in them.
TBox.tile answers the value-time tiles in value order within each day,
covering the box's last day and no value band beyond its upper value.

Format the README examples as Ruff 0.17 does

Ruff 0.17 formats the Python code blocks of Markdown files, so the README
examples take its double quotes and wrapping. The UP038 rule is gone from Ruff
and leaves the ignore list.

Test every aggregator on two overlapping inputs

tests/aggregators runs each aggregator of pymeos.aggregators on two inputs that
overlap in time, so every result holds a stretch where both contribute and a
stretch where one does: the boolean, number and text temporal aggregates, the
three extents, the instant and period counts, the instantaneous time union, and
an incremental aggregation against the one-call form.

Witness: on PyMEOS-CFFI regenerated from MobilityDB master 1eca005aeb the 18
cases pass, and 16 of them fail on the surface of master adbb2ebad1, where each
aggregation starts from a None state the transition wrapper casts unguarded.
Measured: each expected value checks by its definition on the two inputs, the
integer sum being 1, then 1 + 2 = 3 from 2000-01-02, then 3 + 2 = 5 at
2000-01-03, then 2 to 2000-01-04. The suite passes 4471 of 4471.

Aggregate continuous time through the span union transition functions

TimeContinuousUnionAggregator aggregates as TimeInstantaneousUnionAggregator
does: span_union_transfn and spanset_union_transfn add each span or span set to
the state, which starts as None, and spanset_union_finalfn finishes it.
union_spanset_span and union_spanset_spanset are the binary unions of two
values, and MEOS refuses a NULL span set there, so they cannot start an
aggregation.

Witness: the union of [2000-01-01, 2000-01-03] and [2000-01-02, 2000-01-04]
aggregates to {[2000-01-01, 2000-01-04]}, a case added to tests/aggregators;
through union_spanset_span the first add raises TypeError: an integer is
required, from casting the None state the wrapper does not guard. The suite
passes 4472 of 4472.
