v0.7.0 release

This release includes the following improvements and features:

P2P

The new P2P messages sendaddrv2 and addrv2 defined in BIP-155 have been added.

• Bitcoin::Message::SendAddrV2
• Bitcoin::Message::AddrV2

In addition, the following features have been added that are useful for handling P2P messages.

• Bitcoin::Message::Base#from_pkt(message): This method decodes a single P2P message containing the magic bytes and creates an instance of the corresponding message class.
• Bitcoin::Message#decode(command, payload): This method creates an instance of the corresponding message class from the P2P command and payload specified in the arguments.

Improvements

• Improve String#opcode performance: The performance of String#opcode, which is extended with open classes, has been improved. It used to convert all data to bytes, but now String#ord is executed after specifying the character encoding. This change is not expected to have any impact, but if it does, please report it.
• Update the dependent library bech32rb: The version of the dependent library bech32rb has been updated to v1.1.0. It now supports bech32m, the Taproot address encoding.
