use nano_ instead of xrb_

well title kinda explains itself. when using this applet (in my case with nault) the address of the own account is always shown as xrb instead of nano. for some reason tho the target address of a transaction is shows with nano properly

Have all the Nano wallets [with Ledger integration] finally migrated off of the xrb_ prefix? If so, changing the default address prefix would be a simple configuration change here:

ledger-app-nano/src/coins.c

Lines 16 to 18 in 255fef9

    
           .addressPrimaryPrefix = "nano_", 
        
           .addressSecondaryPrefix = "xrb_", 
        
           .addressDefaultPrefix = LIBN_SECONDARY_PREFIX,

honestly no idea (although nanovault is off the table by now), but there's probably no way for the wallet to say whether or not it supports the new prefix I guess.

I think even if not it might be a good idea to at least leave this open as a tracking ticket (and that people see that this has been raised already)

Yes, nano wallets have fully migrated off xrb for quite some time. I think it should be changed asap.

@roosmaa Would be nice if this can be done now with all new users rolling in

	.addressPrimaryPrefix = "nano_",
	.addressSecondaryPrefix = "xrb_",
	.addressDefaultPrefix = LIBN_SECONDARY_PREFIX,
