Compatibility with ARM CPUs

[FliegendeWurst]

Currently, the build fails with lots of errors like:

error[E0609]: no field `rax` on type `&user_regs_struct`
   --> src/main.rs:326:43
    |
326 |     syscall.errno = errno_check(registers.rax);
    |                                           ^^^ unknown field
    |
    = note: available fields are: `regs`, `sp`, `pc`, `pstate`

Edit: Just noticed this in your readme

intentrace currently only supports x86-64, given that the program is currently in beta, PRs for cross compatibility will unfortunately not be accepted until the program is stable enough.

I guess this can be considered a tracking issue then. We'll see how many potential users chime in.

Note, we found this while packaging intentrace for nixpkgs/NixOS: NixOS/nixpkgs#354843

I generally believe cross compatibility at this stage is technical debt but I'm open for counter arguments, I'll leave this issue open
