This guarantees the bitfield is 5 bits, so if someone in the future
decides to shift bits around in the struct it wont break Ballistic.

Stores operand bit positions and types in the decoder metadata. This
makes it way easier to emit IR instructions.

Instead of using strcmp() on each decoded intruction's mnemonic to
translate it, we embedd an IR opcode into the struct. This is a very
barebones implementation and does not cover the entire ARM instruction
set. ARM instructions that does not have an IR opcode equivalent will be
marked with `OPCODE_TRAP` and should be implemented in the future.

The decoder API is now suitable to be made public. decoder.h is the sole
entry point for the decoder and it has been moved to `include/`
