The Triple-T Gradle Play Publisher is a plugin that has a standard

the app dict, then copies any graphics into the fdroid repo

This needs to be run before insert_localized_app_metadata() so that
the graphics files that are copied into the fdroid repo get
properly indexed.

repo/packageName/locale/featureGraphic.png

https://github.com/fastlane/fastlane/blob/2.28.7/supply/README.md#changelogs-whats-new
repo/packageName/locale/changelogs/12345.txt
This will scan the each app's source repo then the metadata/ dir
for these standard locations of changelog files. If it finds
them, they will be added to the dict of all packages, with the
versions in the metadata/ folder taking precendence over the what
is in the app's source repo.
Where "packageName" is the app's packageName and "locale" is the locale
of the graphics, e.g. what language they are in, using the IETF RFC5646
format (en-US, fr-CA, es-MX, etc).
This will also scan the app's git for a fastlane folder, and the
metadata/ folder and the apps' source repos for standard locations
of graphic and screenshot files. If it finds them, it will copy
them into the repo. The fastlane files follow this pattern:
