Make script to/from hex use consensus encoding 

I'm not sure why we do not use consensus encoding currently for encoding
and decoding scripts to/from hex strings. Many tests include hard coded
hex which do not include the length prefix.

- Add a pair of encoding functions to encode/decode to/from hex without
the length prefix.
- Make `to_hex` and `from_hex` expect the length prefix i.e., use
consensus encoding.

This makes the API easier to use because the various encoding APIs can
be use together now eg `consensus::encode_hex` and `ScriptBuf::from_hex`.
