In addition to {@link ParsedBaseLight} this knows if the data is in raw format, i.e. doesn't
have acid metadata columns embedded in the files.  To determine this in some cases
requires looking at the footer of the data file which can be expensive so if this info is
not needed {@link ParsedBaseLight} should be used.
