Lockpick_RCM 🌈 now supports the new key generation introduced in firmware 13.0.0

Additionally, the following was changed:

• added a screenshot button for after the keys finish dumping. Press VOL UP if you wish to save a screenshot, especially when submitting an issue to me
• reboot to Hekate option added to main menu if present on SD
• fixed Mariko dumping both sets of prod/dev keys, this was accidental and the other keyset is erroneous. Erista consoles can still dump both
• no longer require successful EMMC mount to derive keys since it's all done via embedded keygen
• retry keygen on failure for rare edge cases
• fix name of bis_key_source in key file
• set regular RAM clocks while idle, only OC during run
• more verbose errors if encountered when dumping partial keys on Mariko
• embed version in payload so other payloads can check
