`merge` is not documented in the osmium-tool manual

[stouch]

https://osmcode.org/osmium-tool/manual.html does not mention merge command, which leads people to ask it here for example : https://gis.stackexchange.com/questions/242704/merging-osm-pbf-files

Yep, that manual incomplete. Full documentation of all commands is here: https://docs.osmcode.org/osmium/latest/
