0.2.0-beta.3

First, if the light data is not marked as correct, we should not be
parsing it in the first place. This will eliminate errors from
parsing possibly different versioned light data.

Secondly, if parsing the light data throws an exception (from
the SWMRNibbleArray constructor), then we can simply mark
the returned chunk as having incorrect light data - rather than
propagating the exception and causing the chunk to be re-generated.
