feat: Create Python script to track usage of best practices in Mobility Database feeds #72

[cka-y]

This script runs a report to assess

• how the best practices in Add recommended presence: reconciling confusion between best practices and spec google/transit#376 are being used by the community in feeds on the Mobility Database
• if/how the practices referenced in Specify stop times shape_dist_traveled must not exceed the trip shape's maximum distance google/transit#380 and Forbid subfolders in GTFS files google/transit#379 are being used by the community in feeds on the Mobility Database
  This script will help us understand how to best make changes to the spec.

Closes #72
