Bijou64: A variable-length integer encoding

https://www.inkandswitch.com/tangents/bijou64/leb128-noncanonical.png
bijou64 is a variable-length integer encoding that ensures canonicality, preventing multiple ways to represent a number, and runs faster than LEB128 in benchmarks. It uses a tag-based system and bit shuffling to achieve this, making it structurally safer and faster for certain use cases.
