Fastlane

We'd like to upstream our fastlane files for your apps here. As you have multiple apps in a single repo, things get a bit more complicated. For IzzyOnDroid, this is easy: we can freely define the "entry point". But if you want Fastlane be used by e.g. F-Droid.org as well, I would not know where to place the tree(s). They support 3 different locations, but none of them seems to match here: ``` /fastlane/metadata/android/<locale>/ /metadata/<locale>/ /src/<buildFlavor>/fastlane/metadata/android/<locale>/ ``` So if you'd accept it, I'd suggest to use the first variant, just not in the repo root but inside each app's directory. Would that be OK with you? Shall I prepare a PR for that? If a better place can be found, things can be moved anytime (and e.g. F-Droid could copy/symlink the corresponding fastlane tree in their build recipes).
