Support for path convertor {value:path} in FastMCP #220
Description
Currently we do not allow for matching paths in resource templates, meaning that
@app.resource("test://{foo}")
will not match test://foo/bar. This is intended. However at times people want to explicitly match paths. FastAPI offers in this case a path convertor, such that
@app.resource("test://{foo:path}")
would match test://foo/bar.
We should consider adding a convertor approach or something similar to resource templates.

Hello, I'd like to work on this issue.
FastAPI uses starlette converters for this, like here: https://github.com/Kludex/starlette/blob/main/starlette/convertors.py
will implement something similar.

Hello, I've addressed this in the pull request above.
The URI matching logic now supports multiple parameter types, not just
{foo : path}, but also{foo : int},{foo : float},{foo : str}and{foo : uuid}. (defaults to{foo : str})The design is also easily extensible to support additional types in the future.
Please review it.
Thank you!
