Wraps the geohash-rs crate, with a few judicious additions:
- Vectorized versions of the string form decode and encode with one-copy passing
- Integer form decode and encode methods (also vectorized)
- Vectorized round-trip string->int encoding/decoding (i.e. 'wxy321' -> 3465345221n)
NB: there is a small amount of unsafe code in the vectorized methods, involving pointer dereferencing.
Roadmap:
- [x] decode_int, encode_int for u32, u64 variants (vectorized)
- [] decode, encode for u32, u64 variants (vectorized)
- [] simd optimizations
- [] wasm feature fallbacks/multiple targets
- [] passthrough upstream non-vectorized methods
- [] expand environment targets
