Bitcoin: BitcoinAddress for every standard output type, Script, BitcoinTransaction with the legacy, BIP-143 and BIP-341 signature hashes, Taproot key tweaking, Psbt (BIP-174) and Wif keys. BitcoinNetwork selects mainnet, testnet, signet or regtest.

Types

`class BitcoinAddress`	A Bitcoin address of any standard type, tied to its network.
`class BitcoinKey`	A secp256k1 key that signs Bitcoin inputs without necessarily exposing its private key.
`class BitcoinNetwork`	The parameters that make an address or key belong to one Bitcoin network.
`class BitcoinTransaction`	A Bitcoin transaction: inputs spending previous outputs, new outputs, and the witness data SegWit inputs carry.
`class Der`	Strict DER (BIP-66) encoding of an ECDSA signature.
`class Psbt`	A Partially Signed Bitcoin Transaction (BIP-174, with the BIP-371 Taproot fields): the file hardware wallets, multisig coordinators and watch-only servers pass around until every signer has signed.
`class Script`	A Bitcoin script: the locking `scriptPubKey` of an output, or the `scriptSig`, redeem and witness scripts that unlock one.
`class Taproot`	Taproot (BIP-341) key tweaking and script trees.
`class Wif`	Wallet Import Format: a private key in Base58Check, the form paper wallets and `dumpprivkey` use.
