Adding support for fastapi.FastAPI kwargs

[xaviernogueira]

Problem: There are use cases where one might want to customize the fastapi.FastAPI app via keyword arguments (docs here). Previously, there as no option to do so.

Solution: A new, optional, fastapi_kwargs argument for catalog_to_xpublish.create_app()! These arguments are passed directly into fastapi.FastAPI except for "title", which is overridden by param:app_name (a warning if given if these conflict). I added test coverage for this new feature as well.
