Can we add an SD module to log GPS data for use with the Racechrono app?

[Ferrarif-1]

Let BonoGPS transmit GPS data to the RaceChrono app via Bluetooth/WiFi at the same time, and write it to the SD card for backup at the same time, so that even if there is a problem with the phone or app, the original data will not be lost.

There was an issue opened as an enhancement about this #58 , I converted it into an idea so closing this one as duplicate
