SingleFileDisk allows for exporting a file from the onboard LittleFS filesystem to a PC through an emulated FAT drive when connected. The PC can open and copy the file, as well as delete it, but the PC has no access to the main onboard LittleFS and no actual on-flash FAT structures are used. This is handy for things like data loggers. They can run connected to USB power for some time, and then connected to a PC to dowmload the CSV log recorded. It's almost 2023, allow LFN (long file names) on the emulated USB disk. Reduce the disk buffer size to 64 bytes. The buffer is statically allocated so it's always present, even in non-USB disk mode, meaning all apps will pay the RAM price for it. 64 bytes is slower to read but works and saves ~1/2KB of heap for all apps.
