- added the -msse4.1 flag to tools/Makefile - 9 ms -> 5 ms on my machine
- 11 ms -> 6 ms - need to specifically comment out R12LtoRGB to run R12LtoRGBA -- for some reason, UltraGrid prefers the longer R12L -> RGB -> RGBA path

This PR adds SIMD implementations for the color format conversion functions from R12L to RGB and RGBA, aimed to increase performance (the
tools/convert benchmarktool reports an improvement from ~9 ms to ~5 ms for R12L->RGB and ~11 ms to ~6 ms for R12L->RGBA).Although functional, the additions are kept commented out with
#if 0for now.
