CTCaer 0ff121284a hos: add full 13.0.0 support 
- 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
