-todolist:
- * passwords, private keys storage
- * multisig service
- * compatibility with old addresses for restore
- * gui
-
- an account may use one or several MPKs.
- due to the type 1 derivations, we need to pass the mpk to this function
- None : all accounts
- -1 : imported
- 0,1... : seeded sequences
-
- each account has a public and private master key
