Lazily import region modules as required

[adamchainz]

Currently, importing workalendar.registry imports all regions. This wastes time and memory when most programs will work with a handful of regions. It would be nice if workalendar could lazily import modules as requested.

Recently the python-holidays project made a similar change: https://github.com/dr-prodigy/python-holidays/issues/998 . They halved their import time, leaving most in standard library modules.

Here's my import time profiling with python -Ximporttime (blog post), where you can see the long list of workalendar region modules taking significant time.

python -X importtime -c 'import workalendar'
