Port 8bitworkshop sample: crypto.c

[jonathanpeppers]

Port the crypto.c sample from 8bitworkshop. This is a large (100+ KB) cryptography-themed game.

Features needed

• Complex struct types with many fields
• Extensive pointer/array-of-struct patterns
• 50+ user functions (function calling already works)
• Bitfield support in structs
• switch/case with many arms (already partially supported)

Complexity: Very High

The sheer size and struct complexity make this one of the hardest ports.
