Replace Hex Control with Droppers/HexEditorControl

[vector-man]

As future plans are to get IPS Peek running on other platforms, I've decided to eventually migrate the project to Avalonia. The only hex editor I've found that works with Avalonia (as well as WinForms) is Droppers/HexEditorControl: https://github.com/Droppers/HexEditorControl

It is currently under development, but appears to be the best route to get IPS Peek on more platforms.

I'm not sure of the status of the project. So, it looks like either of these are my current best options (both of which still tie it to Windows only for now):

1. keep HexBox and host it in Avalonia

2. Use WPFHexEditor and host it in Avalonia.

I think I'm dropping this idea. Project looks abandoned. Unless I fork and continue working on it, I'm probably better off looking elsewhere.
