* By default...
*
* - Use the slowest -but safest- method for sorting.
* - Folders are sorted to the top.
* - The sort key is statically allocated.
* - No added G-code (M34) support.
* - 40 item sorting limit. (Items after the first 40 are unsorted.)
*
* SD sorting uses static allocation (as set by SDSORT_LIMIT), allowing the
* compiler to calculate the worst-case usage and throw an error if the SRAM
* limit is exceeded.
*
* - SDSORT_USES_RAM provides faster sorting via a static directory buffer.
* - SDSORT_USES_STACK does the same, but uses a local stack-based buffer.
* - SDSORT_CACHE_NAMES will retain the sorted file listing in RAM. (Expensive!)
* - SDSORT_DYNAMIC_RAM only uses RAM when the SD menu is visible. (Use with caution!)
