Enhancement: Make address string in receive screen bigger and formatted into groups of 4-5 chars for better readability

Is your feature request related to a problem? Please describe.
As I mentioned in #1391 , the address string is too small and congested together, it isn't good for readability when you want to verify the address.

In said issue I proposed making the font bigger and formatted into groups of 4-5chars in the send screen confirmation dialog, but I think it should also be done for receive screen, like:

instead of

make it like 8Bbpk NRq4 rW8wu 5tHRJ DnoPt BSyt3... this is far easier to verify, if it's correct.
