- optimised main emulator loop, allowing updates only once every roughly 32,000 instructions.

- optimised memory access patterns, removing unecessary mutability and accesses.
- replaced the standard HashMap with an implementation that uses a faster hashing algorithm.

results:

before:
    - our benchmark program with ~4m instructions would take around for their data to make it to the UI, and a bit over 200ms to actually run

after:
    - our benchmark program with ~4m instructions can run in around 75ms, and the UI receives the update almost instantly.

conclusion:
- emulator performance should be around 2-3x faster than before.
