chunking for uniform grids

[chrishavlin]

This implements a chunking mechanism for 3D data on uniform grids for load_grid. Works for both interpolated and non-interpolated data. The chunk sizes may be set independently of any xarray chunking, and dask arrays do work in this framework (but multiple dask chunks may be contained in a yt grid depending on the provided chunksizes argument.
