Remove roc_Pix_Trim call from PixelThreshold - we get a wrong threshold when always
trimming to 15 by default. Trimming should be handled outside this routine, just as
in every other high level test.
Also use correct variable types (bool instead of int32_t)
Remove some commented out code blocks which just duplicate existing functions.
If you need them back for reference - we have version control.
Add support for inverted pixel addresses.
Bump Software version to 1.17 and update RPC interface.
Add flash file for SW 1.17.
