The new telemetry stuff can send packets with older timestamps, so
sort telem packets read from disk to create an in-order record of the flight.

Instead of waiting for the previous telemetry interval to expire,
immediately switch to the new telemetry rate. This will provide
more telemetry data early in the boost.

v1.0 boards have noisy accelerometer data caused by interactions
between RF transmission and the accelerometer measurements; this noise
generates a negative bias in the accelerometer readings. The net
effect is that the estimated speed is lower than the actual speed,
causing early an apogee estimate.
By increasing the sigma value for accelerometer data, the kalman
filter 'trusts' the acceleration data less, putting more weight on the
barometer data. This causes the estimated time of apogee to be closer
to the correct value.
This reduces the response to changes in acceleration.
This new value is applied solely to TeleMetrum v1.0 boards. v1.1
boards correct for this error, and hence can use the correct sigma
value for the accelerometer.

These are just annoying; when we add the ability to turn stuff on/off
on the fly, we can add them to the list of available items.

An ejection charge looks an awful lot like an extra (really small)
motor burn. Ignore them by averaging the acceleration during
fast/coast using a /64 exponential decay filter.

This reads telem files and displays them in ascii form. It's not done,

With the new boost re-detect code, we can get multiple instances of
boost/fast/coast, so make sure each are displayed in the graph.

Instead of immediately trying to send RDF at apogee, start it after
the usual RDF interval to avoid doing RDF while firing the apogee igniter.

Leave the packet link disabled until we've checked the
accelerometer. That way, we cannot accidentally get to idle mode when
the rocket is on the rail.

TM and Tm go into idle mode if they receive a packet after boot
time. When tebooting the device over the packet link, the packet
master would be (rapidly) polling the device for additional data and
so the device would invariably receive a packet during bootup and go
into idle mode again.
Delay the reboot by a second to give the controller time to disable
the master end of the packet link.
