Lockpick_RCM now supports dumping keys through firmware 15.0.0.

Also added SSL RSA key dumping for those who wish to dump and use the console certificate.

Refactored crypto ops to more closely match what happens in-OS. Lockpick_RCM formerly used some patterns that were different and thus hard to maintain.

Various refactoring and other improvements to readability. More key checks to make sure good data is being saved.
