added CameraView and wired it into a fragment, then connected it with firebasevision. Also completely cleaned up the sendfragment and refactored the way that it manages currency conversions.
This screen is now feature complete. Added actual address and split into 8 numbered parts. There is still a lot left to do but this is the minimum viable solution for now.
next step is to add the numbering to the address parts and then add the real values for the QR code and the address. After that, this screen is complete.
