Prep spiffs for bigger data files

Browse source 
- added spiffs check after flase wipe to force it to update its status
- added spiffs write and append to write in 8192 byte chunks to allow spiffs space to be freed in time.
- fixed spiffs dump to correctly handle issues if it could not allocate bugbuff space.
