check for address gap limit violation

[gorazdko]

Abstract

Close #50

Status

~WIP~ Ready for review:

• [x] final testing
• [x] extracting indexes from compressed and full PSBTs
• [x] noticed also: on verify address screen cancel button does not work if running telnet
  • opened a new issue #60
• [x] when creating a new wallet initialize indexes with -1, so that we correctly browse wallet addresses. If we initialize with 0 we cant know if the address was used already or not
• [x] when browsing wallet addresses we currently allow to go back to address Nr. 1 regardless of max indexes . Should we disallow that or warn that these addresses may have been used already? -> Warnings added.

Looks good! Gonna test tonight.

when browsing wallet addresses we currently allow to go back to address Nr. 1 regardless of max indexes . Should we disallow that or warn that these addresses may have been reused already?

I think we should warn that the address might be reused.

Fixed and force-pushed changes.
