Using with ENABLE_ARDUINO_FEATURES=0

[PetteriAimonen]

I would like to use SdFat on a platform that does not currently have Arduino core support. The SdFatConfig.h has #define ENABLE_ARDUINO_FEATURES 1.

Would it be possible to add #ifdef for this like the other defines, or is there a reason to force it always on?

(I can make a pull request with this and other small changes needed to make it compile if it is welcome)

It is forced on since there is not support for other platforms in the released version of SdFat.

I have used a modified version on mbed, ChibiOS/RT and FreeRTOS but don't plan to release it anytime soon.

Ok, I guess I'll just use a local modified copy then also. Seems to work pretty well with small hacks. For future reference I'll include my changes below. They are quite hacky for now but compile and work:
