Split resource and service types

[pakrym-stripe]

Splits resource object definitions from the resource implementation that contains methods and puts them into separate files.

Adds a typescript test project.

Sanity checked by running:

git checkout master
grep -ohEi 'interface \w+' -R types/2022-11-15 | sort > /tmp/before.txt
git checkout pakrym/Split_resource_and_service_types
grep -ohEi 'interface \w+' -R types/2022-11-15 | sort > /tmp/after.txt
diff /tmp/before.txt /tmp/after.txt
