Fix SPI FrskyD rx frame rate detection

Browse source 
Decrease the minimum on the valid rx frame time window. SPI FrskyD seems to have frames with quite variable timing and if a frame was outside the valid window training would get reset and never complete.  The valid frame timings have no impact on the calculations or operation - they are just sanity checks.
