VESC-scripting native WS2812-driver from LispBM

I made more progress on the native library support. Here you can see a WS2812 addressable LED driver that uses the ST-library as a native position-independent driver. The mistake I made in the video when I ran them at the same time is that I put the function call inside the wrong progn, still in the loop. That is why the function was not tail-recursive and filled the stack. At least it demonstrates that it stopped nicely without crashing the STM32 even with the native libraries loaded.
