CS-5: @ UI: TxCode generation on device
~ Added QRCode for the TxCode
- Added a Third-Party Open-Source MIT Licence QRCode generator from the following link:

https://www.nayuki.io/page/qr-code-generator-library - Created a QRCode component
- Added the QRCode generation functionality in the GuiView
- Added QRCode for both the Pre-Tx-Confirmation (UI Generated) and Post-Tx-Review (CS received)
- Moved the CS TxCode Receive wait "..." from C++ to QML to keep the TxCode empty while wait to avoid displaying the "..." as a QRCode.
- Animated the CS TxCode Receive wait "..."
~ Added development testability for the CloudSync communication
~ Fixed the date change buf file watch to wait for the CS to get the checkin and create the out buf file.
