Add fastalp under Compression section

[x-at-01]

I have added fastalp under the Compression section.

fastalp is a pure Rust implementation of the Adaptive Lossless Floating-Point (ALP) compression algorithm (SIGMOD 2024) for f32 and f64, available on crates.io.

Technical characteristics and benchmark measurements:

• Decompression throughput: Achieves 23.55 GB/s geometric mean across all 37 benchmarks (peaking between 55 and 77 GB/s) in single-core pure-register SIMD decoding. In end-to-end time series decompression benchmarks (graupel), single-core throughput reaches 254 Mpt/s.
• Compression throughput: 3.55 GB/s geometric mean end-to-end compression throughput (4.4 to 6.8 GB/s in regular blocks, up to 20+ GB/s with parameter caching; 169 Mpt/s in time-series encoder benchmarks).
• Compression ratio: Averages 6.83x geometric mean across all 37 benchmarks (2.29x across the 31 ALP paper benchmark datasets).
• Fallback mechanism: Built-in Raw Fallback ensures zero expansion on high-entropy noise sequences.
• APIs: Zero-heap compress_into and decompress_into interfaces.
