Suggestion for flash storage auto config

[nilu96]

Hi attermann,

thanks for you recent updated to microReticulum and Firmware! I just had a test run on my Heltec T114 and had some issues with the automatic flash detection for nrf-based boards. If I got it right, you want a transition from the user having to configure the flash system himself to the system configuring itself, based on the used platform. I think that's a great approach. What's a bit confusing now is, that the USTORE_XYZ build flags are still needed in platformio.ini to build the firmware successfully. Please have a look at my suggested code changes to streamline the new "auto-config" system.

If you would like to incorporate these suggestions, you would also need to remove all USTORE_USE_XYZ flags from microStore and microReticulum as well. As far as I saw it, this would be no big deal. These flags are used in Adapters/Filestore.h files in microStore.

My suggested code changes fix the following issues:

• fix building, if RNS_USE_FS is not set. The cool thing about the new approach is that now you can use a persistent key store in flash but still having the path_tables in heap
• streamline the required build flags: only keeping (HAS_SDCARD and removing USTORE_USE_SD, removing USTORE_USE_XYZ flags in general)

It would be great if you could habe a look at my suggestions. Thanks and keep up the amazing and important work!

PS: If you need any testing for T114, I would enjoy helping you with that.
