Audited & minimal library for Bitcoin. Handle transactions, Schnorr, Taproot, UTXO & PSBT

/**
 * BTC P2P layer from BIP324.
 *
 * Experimental ElligatorSwift implementation:
 * Schnorr-like x-only ECDH with public keys indistinguishable from uniformly random bytes.
 *
 * Documented in
 * [BIP324](https://github.com/bitcoin/bips/blob/master/bip-0324.mediawiki),
 * [libsecp](https://github.com/bitcoin/bitcoin/blob/master/src/secp256k1/doc/ellswift.md).
 *
 * SwiftEC: Shallue-van de Woestijne Indifferentiable Function to Elliptic Curves.
 * Documented in https://eprint.iacr.org/2022/759.pdf.
 *
 * Curve25519 & P-521 are incompatible with SwiftEC. Differences from SwiftEC:
 * * undefined inputs are remapped
 * * y-parity is encoded in u/t values
 *
