Drop hyperscan support

hyperscan is no longer as actively developed as it once was, only works on Intel arch, and crucially its no longer FOSS licensed, so we are essentially frozen at current version

vectorscan is a community fork that works across architectures, is actively developed, and we already have it (mostly) setup for arm

i would propose that we drop hyperscan support altogether and do the work required to make vectorscan work on x86 as hyperscan does now (eg with fat runtime support)
