feat(train): a ride reads the bike's speed and cadence sensor and power meter (ADR 0030, D49)

11d, its sensors: a ride's Record sheet offers the CSC sensor (0x1816)
and the power meter (0x1818), found nearby and remembered as the strap
is; the person's devices are now one map of DeviceKind to DeviceStore.
The service parses CSC and Cycling Power measurements (JVM-tested,
counters' rollover, coasting), writes the wheel's revolutions, the
crank's cadence and the watts to the file and to series of their own.
The recording screen shows cadence and watts; the page the power's
chart, average, highest and normalised power and the cadence's chart and
average; GPX, TCX and FIT carry them. A plan's watts target reads the
power meter too.

The wheel's speed and distance follow. Not tried with a real sensor.
