Fulfill TODO from long ago, I used perf-record (--call-graph dwarf) and detected that add_cycles() was hot enough,
I added 2 optimizations:
- Removed bound checks from array accesses
- Increase the LUT size to include dummy entries for open-bus to eliminate the if check
run_60_frames time: [183.65 ms 183.69 ms 183.73 ms]
change: [-9.4414% -9.2849% -9.1315%] (p = 0.00 < 0.05)
Performance has improved.

It's quite an handy way to log messages from ROMs, so I thought it'd be nice to add it.

Some big refactors:
* improve scheduler performance by using a BinaryHeap
* refactor the scheduler API
* arm7tdmi
* Change struct arm7tdmi::Core struct layout so frequently accesses fields would benefit from CPU cache
* Simplify and cleanup cycle counting by implementing a MemoryInterface trait
* Still not passing many cycle accuracy tests, but I believe it's because I don't have the prefetch buffer yet.
* Timer overflows are now scheduled
* This fixes#111 and fixes#112

This breaks the API of GameBoyAdvanvce::save_state and restore_state methods.
Currently as WIP only SDL2 frontend will adjust.

While saving code re-use, it won't allow flexibility for special casing
specific size bus accesses which are much needed in order to emulate
open-bus and bios reads
