John L. Jegutanis aae2937d11 Add a MerkleBlock construction 
This is a port of the bitcoin-core CPartialMerkleTree and CMerkleBlock classes.
Here they are called PartialMerkleTree and MerkleBlock.

These are useful for SPV clients that wish to verify that a transaction is
present in a specific block in an authenticated way.

Andrew Poelstra 4f74ae61c4 bip32: replace rust-secp key types with rust-bitcoin key types 
We continue to support only compressed keys when doing key derivation,
but de/serialization of uncompressed keys will now work, and it will
be easier/more consistent to implement PSBT on top of this.

Carl Dong a944c7fbd0 key: Use correct error for decoding 
This change also moves the secp256k1::Error wrapper from util::Error to
consensus::encode::Error, since we do not use it anywhere else. We can
add it back to util::Error once we have instances of secp256k1::Error
that are not related to consensus::encode.
