When working with small datasets, we materialized blocks via a `list()` call. This is slow on large datasets. So, we now work only with the iterable of the blocks.

I no longer convert the block_slices iterables into a list. I've also implemented a quick
_parse_schemamethod to extract thepa.Schemafrom the dataset without materializing the first block. These should provide a few good performance improvements for working with real datasets.
