altos/micropeak: Set boost detect to 10m. Add 30s boost delay.

Wait for 30 seconds before even starting look for boost. This provides
an opportunity to close up the airframe, potentially causing pressure
gradients seen by the baro sensor.

Also, require a 10m vertical motion before triggering boost. This
should limit accidental boost detect while capturing any actual flights.
