Update to SdFat 2.0.2, speed SD access (#7779)

Browse Source 
* 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
