se: Upgrade SE and allow SHA calc continue

Browse source 
- Allow SHA to calculate sizes > 16MB and refactor sha function
- Name various registers and magic numbers
- Fix various key access bugs

In a later commit this new design will boost verification times significantly and also allow full SHA256 hashes.
