We can use `package` to rename `bitcoin_hashes` to `hashes` and
`bitcoin_internals` to `internals`. This makes imports more terse with
no loss of meaning.
In some protocols it is preferred to serialize consensus-encodable types
using consensus encoding. E.g. serialize `Transaction` as hex-encoded
string in Json in Bitcoin Core RPC protocol. This change provides
adapter to make this easier.
The adapter allows providing custom byte-to-string encoder for more
exotic cases and provides a hex implementation which should be useful in
majority of the cases.
Should help with #765
