Wherever possible our array indexing logic should be insensitive to dtypes. There is currently some dtype-specific logic in the routine for getting scalars from size-1 numpy arrays. To fix this, this PR removes dtype-specific logic from NDBuffer.as_scalar. Instead, it uses indexing with an empty tuple to get a numpy scalar.
