Allow adding new flags from hexdump

[aedrax]

Is your feature request related to a problem? Please describe.

Currently, you can add a new flag from the disassembly widget from the right click menu and a keyboard shortcut. However, this is not possible from the hexdump widget.

Describe the solution you'd like

Add an action to the right click menu in the hexdump widget for adding a new flag. Ideally, this will also correspond to a keyboard shortcut which is synchronized with the keyboard shortcut from the disassembly widget.

I am part of the team at Purdue working with Professor @SantiagoTorres.

I've updated the pull request titled "WIP: Added option to add new flags from hexdump #2932" with the new functionality for adding flags from the hexdump view. I've also included images in the PR to demonstrate how this feature works.
