Initial release

BTC transaction utils is a small library that helps to create multisig addresses
and to swiftly sign some types of segwit transactions as well as to check the
existing signatures, if required.

Manipulations with segwit transactions are quite complicated, so the main goal
is to provide a simple and clear solution for the most common operations
as mentioned above.

Features

• Creating of the redeem script, which is used in the multisignature transactions.
• Creating and checking of the applied signatures of the p2wsh inputs.
• Creating and checking of the applied signatures of the p2wpk inputs.

Note: This library supports only the SIGHASH_ALL type of signatures.
