bltouch: Add an extra 200ms delay to the initialization process 

On a reset, the mcu.py code may have sent an initialization message to
the bltouch, which needs time to complete.  Add additional time during
the bltouch setup to avoid a race with these two times.  This avoids
some "timer too close" errors that users of fast host machines were
reporting.
