Emulate the Kria alt firmware for White Whale

Tasks:

• [ ] Link in Kria as submodule, get it to build in mock_hardware system.
• [ ] Enable reuse of the WW widget and core classes, but swapping firmware and SVG graphics.
• [ ] Decide whether alt firmwares are a completely new module or a right-click swap like the alt firmwares for Audible modules? Probably a completely new one, saving module memory to the rack patch would interact weirdly with runtime firmware swaps.
• [ ] Create SVG panel graphics for Kria.

Ansible Kria has a substantial number of new features now so it probably makes sense to put this effort into Ansible instead.
