btcOperator v1.1.2: multisig utils

Browse Source 
- Added decodeRedeemScript: decodes the given redeemScript and return {address, pubKeys, required}. (optional bech32; default=true. if true return bech32 address. if false returns legacy multisig address)

- Added convert.multisig2multisig: convert from one multisig address to another. (optional target_version; default=btc-multisig-version)
- Added convert.bech2multisig: converts multisig bech32 address to multisig address. (optional target_version; default=btc-multisig-version)

- Added encodeLegacy, decodeLegacy, encodeBech32, decodeBech32 to util
