armv7 architecture support

[brandonros]

I'm opening this because I'm probably going to have to figure out how to implement it.

If you have any tips or general advice overall on where to start other than src/arch, I'd love to hear it. Thanks in advance.

Sorry for not getting to this issue, I've been away for a bit.

I'd have to take a look at the codebase to figure out the best way to start.

First thing though, would be to ensure all of the current dependencies work on armv7, otherwise they'd have to be replaced or rewritten for that target.

I'll try to look more at it sometime next week to hopefully help in your effort!

I cleaned that up and moved it here: https://github.com/brandonros/arm-retour-rs

Nice work! This should be a good basis for adding it to this crate. I'll see if I can adapt it to the structure of this crate.

Has there been any progress on ARM support?

I haven't had the time to work on this implementation, but I'm open to reviewing any PRs
