fix(train): the wheel is learnt from rides GPS covered, whatever its size (ADR 0030, D56)

Browse source 
The measure was held to GPS making 90 % of the wheel's way at the
circumference taken, 2105 mm to start: a real wheel under some 1.9 m fell
short of it on every ride and was never learnt. A ride now measures where
precise fixes followed it for 95 % of its moving time, its quotient between
1 and 3 m as one typed may be.
