altos: Make telemetry interval more consistent
Instead of using a delay between telemetry packets, use a telemetry
period and compute an appropriate delay each time. This requires
changing the ascent telemetry from a 50ms delay to a 100ms interval,
to provide a regular 10 packets-per-second rate. Before, we counted on
the telemetry packet taking about 50ms to send so that we would
receive about 10 per second.
This also eliminates delays during descent for RDF tones -- those will
get transmitted in the interval between telemetry packets without
interrupting the spacing of those packets.

altos: Configure packet size from send/recv parameters.
Instead of setting the packet size at configuration time, use the
provided packet size to the send/recv functions to configure the
radio. This eliminates many configuration calls, leaving us with 'RDF'
mode and 'packet' mode, the latter working for telemetry and the
bi-directional link.

altos: Don't init packet slave on TD. Make slave start optional
Oops. TeleDongle was starting the packet slave code, which kinda
wrecked its ability to receive telemetry packets. This patch simply
removes the packet slave code from teledongle as it cannot be used
(yet), it also makes the packet slave code initialization take a
parameter which controls whether to start that by default; in the
future, perhaps TeleDongle will gain a command to start packet slave mode.
