Loading fields and other custom slices for structured arrays

[jakirkham]

After discussion in issue ( https://github.com/alimanfoo/zarr/issues/110 ), a particular interesting case of slicing structured arrays stored in Zarr came up. In particular, it would be great to be able to slice particular field(s) (e.g. z[:, 'foo']). Related to this, it would be great if a particular range or index could be used (e.g. z[:5, 'foo'] or z[1, 'foo']).

Thanks for raising, I think this would be a nice add.

Of course.

An interesting extension to this would be handling slicing of the record too (e.g. z[:5, 'foo', 1]) once issue ( https://github.com/alimanfoo/zarr/issues/111 ) is fixed.
