SciQLop/speasy_proxy: v0.20.2

Dependencies

• speasy 1.8.4. Its proxy client asks for compression=blosc (SciQLop/speasy#373), which this server has served since 0.20.0: per-array byte-shuffle + zstd, about 40% smaller than whole-pickle zstd on field data and several times faster to decode. speasy's cache version is unchanged, so existing caches are kept as they are.
• pysciqlop-cache 0.2.2. Value files are never unlinked inline any more: triggers queue them in a trash table in the same transaction as the row change, so a rolled-back delete can no longer lose a value. A value that can't be written raises instead of being silently dropped. Opening an existing cache only adds two triggers; a cache round-trip 0.1.16 → 0.2.2 → 0.1.16 → 0.2.2 kept every value and left no orphaned files.
