keys must be lexicographically sorted before creating the redeem script for the address. To generate a P2SH address, the procedures is as follows:
- all the extended public keys of the members of the wallet must be know
- all the extended public keys must be derived to the desired path (for example `m/48'/0'/0'/0/1` for the second external address)
- the resulting public keys must be sorted lexicografically
- the redeem script must be composed, and its hash calculated, as defined in BIP16
