xxHash v0.8.3

xxHash v0.8.3 is a maintenance update, featuring a bug fix and several quality of life improvements.

XXH3_128bits_withSecretandSeed()
Corrects an edge case (#894) that could generate invalid results. Users of this function should upgrade. Thanks to @hltj for the report and fix.

Runtime Vector Extension on x86
xxhsum automatically detects and employs the best available vector extension (SSE, AVX, etc.) on x86/x64 cpus. Previously, this required an explicit build macro; it is now enabled by default. Maintainers can still control it manually, and can disable it with DISPATCH=0.
--filelist / --files-from
Accepts file names from a text file or stdin, simplifying bulk hashing. Kudos to @Ian-Clowes for the idea and implementation.
Short GNU Format for XXH3
A new -H3 mode generates XXH3 64-bit hashes with a XXH3_ prefix, neatly distinguishing them from XXH64. The symlink xxh3sum defaults to this mode.

LoongArch SX SIMD Support
Includes an optimized LoongArch SX implementation of xxh3 (courtesy of @lrzlin).
Extended Platform Coverage
Validated builds for AIX OS and SPARC CPUs.
