SDfat lib with GCS upload

[bhupiister]

Standard SD library was giving issues with Shared SPI bus ( display ili9341 and SD card) on M5Stack Core2
Link to Issue
So I had to shift to SdFat library by greiman
Some good things I noticed about this library

1. Good access speed
2. Faster upload to Google cloud storage (2 Mb file, 9-10 sec)
3. Ability to run SdFat on Shared SPI bus

@mobizt Can you create an option to use this library in a future release?

If someone wants to try. Here is the short snippet, add the below code snippets to GCS.cpp

#include "SdFat.h"
#define SPI_CLOCK SD_SCK_MHZ(10)
#define SD_CONFIG SdSpiConfig(TFCARD_CS_PIN , SHARED_SPI, SPI_CLOCK)
SdFs sdfs;
FsFile direc;
FsFile fileInt;

The new version is available with bugs fixed and many features added included add support SdFat.

Please update and check the example.
