Fix patches for dump with offsets

[Impact-I]

The author of the article provided code for extracting offsets for the latest engines https://medium.com/@ostorlab/flutter-reverse-engineering-and-security-analysis-41433f5671f3

The approach from the Ostorlab article (reading offsets from instructions_table_.rodata()) was already implemented in patch_source() for ver > 38 (newer Flutter versions). However, it produces incorrect offsets (0x80) for some versions like Flutter 3.24.0 — see #324.

The next step is to investigate the InstructionsTable struct changes across Dart versions to determine why pc_offset doesn't return the correct value for certain engine builds.
