Change default chunksize to 1MiB (#229)

Browse Source 
This change makes the original 16MiB option not the common option.

It also changes the names of the defines to
  SNMALLOC_USE_LARGE_CHUNKS
  SNMALLOC_USE_SMALL_CHUNKS

The second should be set for Open Enclave configuration, and results in
256KiB chunk sizes.  The first being set builds the original 16MiB chunk
sizes.  If neither is set, then we default to 1MiB chunk sizes.
