fatfs v0.14 October 14, 2019:

- Added support for 64-bit LBA and GUID partition table (FF_LBA64 = 1)
- Changed some API functions, f_mkfs() and f_fdisk().
- Fixed f_open() function cannot find the file with file name in length of FF_MAX_LFN characters.
- Fixed f_readdir() function cannot retrieve long file names in length of FF_MAX_LFN - 1 characters.
- Fixed f_readdir() function returns file names with wrong case conversion. (appeared at R0.12)
- Fixed f_mkfs() function can fail to create exFAT volume in the second partition. (appeared at R0.12)
