ndi.python.clearCommandCache
CLEARCOMMANDCACHE - forget where NDI-python's commands were found
ndi.python.clearCommandCache() empties the cache that
ndi.python.findCommand keeps, so the next lookup searches again.
Equivalent to ndi.python.findCommand('clear'). ndi.python.install
calls this after installing or uninstalling.
