[MAINT] update packaging

[Remi-Gau]

• update packaging so that install as a subpackage of pybids is possible (fixes Package Import is not possible.  #12)
• allow to use a git submodule as "package data" (fixes allow git submodule with mustache templates to be used as package data #26)

Can the whole content of setup.cfg be moved to pyproject.toml?

[Remi-Gau]

@effigies

seems that subpackaging still works using setuptools: which I remember you said was not possible anymore.

if you suggest that we use hatch instead (or something else), will it still be possible to use versioneer?

if you some time could check this PR?
more specifically:

• does the packaging setup look sensible to you?
• can what's left in the setup.cfg be transferred in the pyproject.toml?
• there seems to be a duplication or purpose with what's in the MANIFEST.in and what is package data in the setup.cfg

pybids-reports/MANIFEST.in

Line 3 in 0532cac

recursive-include bids/ext/reports/config *.json

setup.cfg: ⬇️

[options.package_data]
* =
    config/*

@tsalo
merging this

FYI packaging is now done with hatch.
