- 13.0.0 master key support
- Derive proper keys per mkey revision instead of the latest for Erista devices
This allows to identify issues with Pkg1/Pkg2 mismatch and also allows using old Exosphere/Atmosphere versions.
- Simplify pkg2 decryption because of proper keys
7.0.0 is still done via 8.1.0 mkey because of an Exosphere bug.
- Add nogc patches
- remove any reference to sept and parsing of it
- completely refactor and simplify keygen
- use new Atmo tsec keygen for 7.0.0 and up
- simplify all info/tools that depend on hos keygen and bis keys
