Support of Freenove CAM S3, add file explorer

Added support for freenove cam S3 (note if you have very poor wifi speed, I advise you to unsolder or cut the pin connectors from the card).
Adding a file explorer from the web interface.
I use two different versions of micropython, for esp32, I stay on version 1.20, which links without problems, for esp32 s3, I migrated to a very recent version.
I added a plugin that allows you to control a sound player, the goal is to give the impression that the house is occupied. I have not documented this project, if you are interested let me know.
The Linux camflasher works again.
In the camflasher, I added the possibility of loading several binaries at different addresses.
If you want to use certain part of the platform on esp32 without spiram, you will have to comment the unnecessary parts in the main.py to limit ram memory consumption.
