Cw 598 fixes for electrum based wallets (#1344)

* fix: address book addresses, bch builder, exchange all fee estimation, bch coin control

* feat: new error framework for Electrum messages

* build: cw_bitcoin.dart

* feat: error improvements, localization, fix exchange amount mismatch

* chore: misc comment & print [skip ci]

* feat: refactor & simplify sendAll vs regular tx estimation and creation

- Since there were so many conditions inside a single function to alter its behavior if sendAll or not, it is easier and more readable to have separate sendAll and estimateTx functions that behave separately

* fix: wrong LTC dust

* feat: fee rate confirmation

* fix: wrong createTrade value when isSendAll is enabled

* fix bitcoin cash address parsing [skip ci]

* fix: form no amount validator, address book with multiple entries, exchange all below min error

* fix: improve string, fix sending with dust inputs at the top

* fix: two change outputs when re-estimating

* fix: sendAll with a little dust adds fees

* chore: sanity check [skip ci]

* fix: if the fee is higher than estimated

* Minor enhancement [skip ci]
