Subject: [PATCH]  floCrypto v2.3.4: multisig address

- Added getMultisigAddress(pubkeys, required_sigs): returns a multisig address from given pubkey list and required signatures
- Added decodeRedeemScript (redeemScript): decodes the given redeemscript (of multisig)
- Updated validateFloID: now validates FLO regular and multisig address. optional argument regularOnly(default=false) if true validates only FLO regular address.
