* Update to upstream SdFat 2.0.2 Increases the read/write performance for SD card accesses by a significant amount, up to 5x (3+MB/s) in testing. Fixes #7772 * Add SDFS::availableForWrite handler Peek into the sector cache to determine the maximum number of bytes that can be written w/o needing a (slow) SD operation. Fixes #7650
Arduino "class SD" shim wrapper
This is a simple wrapper class to replace the ancient Arduino SD.h access method for SD cards. It calls the underlying SDFS and the latest SdFat lib to do all the work, and is now compatible with the rest of the ESP8266 filesystem things.
