Component: BufferedLog

This components supports high frequency logging. While one buffer is filled by application, the other buffer is written to EEPROM as a background task. It supports the LogData interface, but only allows individual appends up to the buffer size (currently 128). It is expected that each append will be small (e.g., a single or small group of sensor samples)
