Add profile options to select between different UPI ids

[YUDHPK]

1. Add an option to save more than one upi id for scanner generation along with default upi id selection
2. FOSS Software and uploading it to f-droid makes it more accessible and available to others.
3. Add an option to hide the amount in the scanner page as the user can view the amount in his or her phone anyways. (Avoids dispute in some cases)
4. Make an option to display the QR's name below the QR itself
5. Upon opening the app there should be an option to open keyboard automatically

And thankyou for making such an app
