SPIFFS : FIXES FS corruption against high numbero f current losses, high number of files manipulation. FIXES LOG_BLOCK erasing handlers. FIXES Garbage Collector. Overall, SPIFFS should now be WAY MORE resilient to any form of misbehavior. In case of corrupted filesystem (should still be readable !), spamming 'mem spiffs check' from the client will ensure at least 2 new free 4k blocks each tile (if number of LOG_PAGE available is enough) and in the same pass will move/reorganize the LOG_PAGES of contextual blocks.
