Image types the modules should support

[Eric.VanAlst@…]

In the modules SDR-02, there is no specification of the types of images the
module processing needs to handle. The current implementation makes assumptions
of psF32 for the pmNonLinearityLookup. Should the SDR be updated to specify the
specific image types each of the modules will need to support?

[Paul Price]

Added sentences to the modules SDRS to specify types, as listed below.

pmSubtractBias: The input image may be of type U16, S32, or F32. The bias image
must be of the same type as the input image.

pmNonLinearityPolynomial, pmNonLinearityLookup: The input image may be of
type U16, S32, or F32.

pmFlatField: The input and flat-field images must both be of type F32.

pmMaskBadPixels: The input image may be of type U16, S32 or F32. The mask image
must be of type U8.

pmSubtractSky: The \code{mask} shall be of type U8, and the input image,
\code{in}, must be of type F32.

pmReadoutCombine: The \code{inputs, zero} and \code{scale} may be of U16, S32
and F32 types, and must all be of the same type. The \code{output} shall be
of the same type.

Object detection stuff: images are of type F32 and masks are of type U8.

MSDR-03 has been update to contain type information.
