Could you elaborate on what the GitHub repository "bitcoinjs/bitcoinjs-lib" entails? I'm curious about its purpose, functionalities, and significance in the
cryptocurrency landscape. Is it a comprehensive library for Bitcoin-related operations? Does it provide tools for transactions, key management, or other Bitcoin-specific tasks? How widely adopted is it in the community? Also, is it actively maintained and updated to stay compatible with the latest Bitcoin network developments? I'd appreciate a concise yet comprehensive overview of the repository and its role in the Bitcoin ecosystem.
