altos: Finish ms5607 support
This has the MS5607 polling once each tick for pressure and
temperature and then saving that in a global variable. The command UI
provides for dumping the prom data so that an eeprom file can have
raw sensor data along with the conversion factors necessary to compute
useful values.
