CSV optional Ray Attributes

[ichinii]

Add Support for optionally writing/reading Ray Attributes to/from.

CSV is a human readable File Format. We should make it as readable as possible. CSV currently is difficult to read, because Ray Attributes are written, that May Not be of interest for the User. This could be improved by letting the User decide written Attributes on their own.

Performance would also benefit from writing less Attributes.

Note that writing specific Attributes was Support Prior to the Ray structure of Array Update. a new format system was introduced, that should be used here
