We had been using an ancient version of "cryptography" so far in our p4a fork, however it is not compatible with OpenSSL 3.0. (Previously we were building it with OpenSSL 1.1) Bumping "cryptography" is difficult, as building new versions of it from source requires a full rust toolchain. Instead, this commit switches to "pycryptodomex", as a replacement, which is much easier to build from source.
python-for-android local recipes
These folders are recipes (build scripts) for most of our direct and transitive dependencies for the Android app. python-for-android has recipes built-in for many packages but it also allows users to specify their "local" recipes. Local recipes have precedence over the built-in recipes.
The local recipes we have here are mostly just used to pin down specific versions and hashes for reproducibility. The hashes are updated manually.
