Since it is known that libtiff produces other sample format variants we do not support, represent these as variants. This also allows returning the sample formats in errors so that composition of formats and known and unknown formats are clearly reported.

Formats
This table lists photometric interpretations and sample formats which are supported for encoding and decoding. The entries are ColorType variants for which sample bit depths are supported. Only samples where all bit depths are equal are currently supported. For example, RGB(8) means that the bit depth [8, 8, 8] is supported and will be interpreted as an 8 bit per channel RGB color type.
