feat: list available profiles directly

[jenhagg]

Purpose

Simplify the process to use a custom profile - instead of requiring a local version.json, we can just list the existing files.

What the code is doing

Extracts the profile version from the filename, for files in the raw/{grid_model} folder. We currently assume this folder exists, and the files conform to the current naming convention.

Testing

Ran it locally, added a new profile, got expected result:

In [17]: ProfileHelper.get_profile_version_local("usa_tamu", "demand")
Out[17]: ['vJan2021', 'vFeb2021']

Time estimate

10 min

Any windows users want to do a quick test? @danielolsen? :)

Works on Windows too!

>>> from powersimdata.data_access.profile_helper import ProfileHelper
>>> ProfileHelper.get_profile_version_local("usa_tamu", "demand")
['vJan2021', 'vSep2021']
