Feature request: updating c_libs interface header

[tmgofer]

Hi, Are you planning to extend https://github.com/vedderb/bldc/blob/master/lispBM/c_libs/vesc_c_if.h and publish more functionality that will be accessible to c_libs? There are many functions that can be invoked in LISP, but are not published for native libraries (eg. foc-beep calls mcpwm_foc_beep, which is not exposed in vesc_c_if.h. The same with set-aux) Also, just a few settings can be set by VESC_IF->set_cfg_[float/int] ... Please consider extending the interface.
