Addresses for example #105. In short, some APKs don't contain v1 scheme signatures, meaning the usual approach of forcing a v1 fallback and patching that doesn't work for those.
Patches for example:
This implements full v3 patching. Probably a bit of redundant code between the two versions. It does do a fair few things differently like digests or proof-of-rotation, but those are documented.
