vectorscan/5.4.12

What's Changed

Multiple changes since last release, this will be the last 100% ABI and API compatible with Hyperscan release. Next versions will include major refactors and API extensions, it will be mostly backwards compatible however. Without particular order, platform support is now:

Linux (x86, Arm, Power)
FreeBSD 14 (x86, Arm, Power)
MacOS 14+ (x86, Arm)

In total more than 200 configurations in the CI are tested for every PR.

Other features:

Fat Runtime supported for Arm as well (ASIMD/SVE/SVE2).
Initial implementations for Arm SVE/SVE2 algorithms added, thanks to Yoan Picchi from Arm.
SIMDe support added, used as an alternative backend for existing platforms, but mostly interesting for allowing Vectorscan to build in new platforms without a supported SIMD engine.
Various speedups and optimizations.
Cppcheck and clang-tidy fixes throughout the code, both have been added to CI for multiple configurations, but only cppcheck triggers a build failure for now.

Various bugfixes, most important listed:

Speed up truffle with 256b TBL instructions (#290)
Fix Clang Tidy warnings (#295)
Clang 17+ is more restrictive on rebind on MacOS/Boost, remove warning (#332)
