Merge rust-bitcoin/rust-bitcoin#4316: Improve the script hex APIs
5d5a19793aRun the formatter (Tobin C. Harding)2b72f1f30bMake Lower/Upper hex print scripts with len prefix (Tobin C. Harding)c27b95fb0dMake script to/from hex use consensus encoding (Tobin C. Harding)f4bc58dc48bitcoin: Add a script encoding example (Tobin C. Harding) Pull request description: Done while investigating #3910 - this PR is quite invasive. - Patch 1 adds an example that shows the current behaviour of various API calls for converting scripts to/from hex. - Patch 2 adds a pair of functions that do not use the length prefix and makes script to/from_hex use the prefix. - Patch 3 makes `LowerHex` and `UpperHex` use the len prefix also - Patch 4 runs the formatter Explicitly keeps serde untouched - i.e., without the len prefix ACKs for top commit: apoelstra: ACK 5d5a19793aae73ff09d7064455a1a995eb796c28; successfully ran local tests Tree-SHA512: dbbec372ea7b01818fce68ffb807a4531f068e10147e8bedf37b77f66a068a628e380549c379c061b868973e97806ada59729248b03bbd1cf6809f6098170cb6
