wallet: add remark14 option to migrate UTXO assets to N3

Browse source 
N3 migration works via sends to blackhole ANeo2toNeo3MigrationAddressxwPB2Hz
address with Remark14 attribute set to target N3 address [1]. This option
allows to create such transaction (but it doesn't check target address in any
way, if you make a mistake there you'll lose your assets forever). It works
like this:

$ neo-go wallet transfer -p file.wallet -r https://rpc-node:10331 --from AZ81H31DMWzbSnFDLFkzh9vHwaDLayV7fU --to ANeo2toNeo3MigrationAddressxwPB2Hz --asset NEO --amount 10 --remark14 NVTiAjNgagDkTr5HTzDmQP9kPwPHN5BgVq
