fix: ARMv7 addresses

[cfung89]

Hello, here is a small fix to make ARMv7 addresses compatible.

For LDR A1, =addr:

Before:

(program ; [0, 0] - [1, 0]
  (instruction ; [0, 0] - [0, 13]
    kind: (word) ; [0, 0] - [0, 3]
    (ident ; [0, 4] - [0, 6]
      (reg ; [0, 4] - [0, 6]
        (word))) ; [0, 4] - [0, 6]
    (ERROR ; [0, 8] - [0, 9]
      (ERROR)) ; [0, 8] - [0, 9]
    (ident ; [0, 9] - [0, 13]
      (reg ; [0, 9] - [0, 13]
        (word))))) ; [0, 9] - [0, 13]

After:

(program ; [0, 0] - [1, 0]
  (instruction ; [0, 0] - [0, 13]
    kind: (word) ; [0, 0] - [0, 3]
    (ident ; [0, 4] - [0, 6]
      (reg ; [0, 4] - [0, 6]
        (word))) ; [0, 4] - [0, 6]
    (ident ; [0, 8] - [0, 13]
      (reg ; [0, 8] - [0, 13]
        (address))))) ; [0, 8] - [0, 13]

Thank you very much for this great project! I apologize for opening so many PRs in a short amount of time, but I already had a few changes done, and thought it would be best to have different changes in different PRs. Please let me know if there are any changes/improvements you would like me to make.

Hi! I'm just gonna write this here once, instead of on every PR:

Thank you very much for submittimg your changes here instead of just quietly using them yourself. I will try to review them as soon as I can. In the meantime, just kindly make sure your changes don't break any inputs of asm dialects that were supported before. I'm not actually sure the tests are enough for that, so some manual testing won't hurt.

Hi, thank you very much! I did a couple manual checks with a few examples longer examples found online, in x86 and ARM64, and everything seems to be the same (and even less errors in ARM64).
