stegoveritas-binwalk: capstone 5.x incompatibility (CS_ARCH_ARM64 renamed) + missing dependency #45

Problem

stegoveritas-binwalk (the bundled binwalk fork) fails to import on systems with capstone ≥ 5.0.

binwalk/modules/disasm.py references capstone.CS_ARCH_ARM64 as a class-level attribute, evaluated at import time:

Architecture(type=capstone.CS_ARCH_ARM64, ...)

In capstone 5.0, CS_ARCH_ARM64 was renamed to CS_ARCH_AARCH64. This causes an immediate AttributeError before any test or analysis runs:

AttributeError: module 'capstone' has no attribute 'CS_ARCH_ARM64'. Did you mean: 'CS_ARCH_ARM'?
  File "binwalk/modules/disasm.py", line 60

Additionally, capstone is not declared as a dependency of stegoveritas-binwalk, so it is not installed automatically.

Discovered while packaging stegoveritas for Gentoo Linux: pentoo/pentoo-overlay#2923

Fix

Add a compatibility shim at the top of binwalk/modules/disasm.py (after import capstone):

# capstone 5.x renamed CS_ARCH_ARM64 to CS_ARCH_AARCH64; support both.
_CS_ARCH_AARCH64 = getattr(capstone, 'CS_ARCH_AARCH64', None) or capstone.CS_ARCH_ARM64

Then replace both capstone.CS_ARCH_ARM64 references in ARCHITECTURES with _CS_ARCH_AARCH64.

Also add capstone to the stegoveritas-binwalk package dependencies.
