Add support for BPS patches

[HimoriK]

Currently does not support .bps files.

Here's the documentation for the spec. I'll look it over and see what I can do: https://github.com/blakesmith/rombp/blob/master/docs/bps_spec.md

[vector-man]

Looking at the spec, it appears that some of the data will not be viewable, unless a file is linked (as some of the data is processed using the target file.) For those instances, it would only display the operations, without data (unless you open a target and link it.)

If it's possible to interact with the IPS file and compare changes this is fine, unless there is another way.

Okay, I think it's doable. I'll just show a blank hex view in those cases. But I may need to rename the project to something a bit more appropriate soon.
