Select disassembler crate(s) for integration

[mjhouse]

At some point, this library will include the ability to modify function assembly programmatically. To do this, I'll need to be able to disassemble the assembly, expose instructions somehow, and reassemble for multiple architectures. If no good disassembler can be found that handles all architectures, I'll need to piece together a solution or write my own (a huge task).

This issue is for collecting crates that disassemble:

Name	Architecture	Notes	Url
iced	x86 64/32	Fantastic crate, but only for x86	link
bad64	Arm 64	Wrapper, lightly supported	link

(I'll add more as I find them)

I've decided that since-

1. This is a learning project anyway (no due dates, no deadlines)
2. There's no great, pure, safe Rust ARM disassembly crates that I've found
3. I have different goals (read AND write instructions programmatically)

I'm going to write my own disassembler for x86 and then extend it to include support for ARM/ARM64.
