altos/micropeak: Clock micropeak at 250kHz to save power
This reduces average current consumption from 2mA to .4mA. This
makes the battery last longer, but also gets the current under
something that the typical CR1025 battery can support. Would be nice
to reduce current even further; cheap CR1025 batteries still seem to
fade a bit at this current level.
