initial fastlane structures from IzzyOnDroid

[IzzySoft]

this PR provides you with a "fastlane starter package" – to give it into your hands to define how your app is presented, and make it easy to keep descriptions & graphics in sync with your development. Some notes to sum them up in a place easy to find for you:

• the IzzyOnDroid Fastlane Documentation can guide you with maintaining the structures here
• take special care for limits, e.g. per-release changelogs can have max 500 chars, full_description.txt max 4,000 chars, graphics must have specific aspect ratios etc.
• you can have "bigger graphics" here; the IoD updater takes care to resize/optimize them as needed
• for the full_description.txt here I've used HTML compressed into a single line, to prevent the fdroid software converting each line break to a <br>. The tags used for this are supported by F-Droid.org as well, and to my knowledge even by PlayStore. Feel free to switch to what the above linked documentation describes as "Markdown Lite" if you prefer.
• whenever you add a new "type" of metadata that has not been there before (e.g. the first changelog, a featureGraphic if it wasn't yet present), please let us know so we can check and enable it.
• Details on all this in the linked documentation.
• Once merged, your changes will be synced whenever a new release is pulled in here – to make sure it stays up-to-date with the app itself.
• Should you have questions, be welcome to ask 😉

And now: Enjoy!

@IzzySoft These screenshots are from the previous version. Are you sure you want to use these instead of the new ones?

@nfdz of course I'm not sure 🤣 That's one of the reasons I'm sending you this "starter package" (with what is set up at our end currently): so you know where to put things, and modify them as needed (here, e.g. replace the "old screenshots" with up-to-date ones). We have more than 1k apps in our repo; with our small team, it's impossible to keep up with updates to screenshots and descriptions – which is much better done by those maintaining the apps, as they know best how these things should be.

Feel free to replace the screenshots either before or after merging 🤗 Same for the app description, if you think it needs updates.

Understood, thanks for the clarification 👍

[IzzySoft]

Thanks for merging 🤗 All set at our end as well, so any changes you might make in the future, should be pulled along whenever a new release is pulled in.
