I suggest to split PR to standalone commits to simplify review.

I also checked this PR now and it's indeed quite huge. Could you add them to separate commits or feature per PR? Also file src/asm2cfg/asm2cfg.py is growing in size quite a lot. You're welcome to try split some parts of it like you already done with utils.py. If not then this can be done on later PRs as well. One problem with the splitting is making sure this project still works as a GDB plugin. If I remember correctly there might be some problems with import paths.
