* Removed -HUP so the default -TERM signal is sent instead. - hyperiond only listens for TERM and INT. HUP is often used to get an exe to reread its config Changed pgrep to add '-x' so it wont partial match on the exe name. - I have multiple instances with multiple hyperiond-instance1 names - this ensures the service script only kills the right process * reversing errant change to hyperion.systemd.sh * cleaned up a couple of compiler warnings * moved bitpair_to_byte initialiser to (hopefully) work with older GCC * compiler warning in udp driver removed some tabs in ws2812b.cpp * formatting - spaces to tabs Former-commit-id: 42cc7325177c9fcc3d1bd29cbfe72f02118d3233
