On the Way to Data Shuttle, Pull from logged SD Card data for batch transmits (e.g. LoRa, WiFi, 4G, etc)

[udellc]

Is your feature request related to a problem? Please describe.
I'm not exactly sure how batch is being conducted, so maybe this is already being done. I was looking at some examples online

That describe pulling data from logged SD data to make batch transmits. This seems much more robust than saving data in RAM during operation and then transmitting that batch, because if power is interrupted we lose that data in the transmit cycle. AND I'm hoping to have code that would put us on our way to some kind of wireless data shuttle process. This would entail a transfer from SD over Wifi to a connected computer (AP or client mode, likely AP) without having to open the case. We might use FTP to do that?

Describe the solution you'd like
The ability for a PC app to send a signal to the Loom logger to initiate a File transfer. Ideally, an interface to see the available files on the SD card and upload or download files to/from PC to the SD on the Loom logger.

Describe alternatives you've considered
Batch uploads to MongoDB and then using Compass to download the files. Not as stable AND many places don;'t have internet networks.

Additional context
I know this looks like I'm asking for 2 different features. What I'm really asking is that our protocols for handling data transfer are optimized with this future functionality in mind.
