Andrew Champion f92be13f6c Factor tags into own module 
Tag representations are not decoder- or encoder-specific, so should live
in their own module accessible to both for reuse. The decoder::ifd
module remains since this module is mainly dedicated to decoding the
IFD.

Andrew Champion d510a9f4ab Strictly handle expected tag value types 
Resolve several TODOs where tag values were cast from u32 without checks
by providing generic methods that error when the value fails casting to
the desired type. In addition to being more correct, this simplifies and
shortens decoding logic.

Remove `find_tag_u32` and `find_tag_u32_vec` as they are now redundant
and a GitHub code search found no usages outside copies of
`image-tiff`.

Andrew Champion e5d2e7862c Parse all homogeneous bit depth RGB(A) color types 
Make the behavior of RGB and RGBA like Gray in returning ColorTypes for
all homogeneous bit depths, even if those depths are not 8, 16, 32 or
64. Note that this does not change which color types can actually be
decoded.

Andreas Molzer 7b672998db Get rid of num-traits crate 
Turns out the only use was as a private bound which was unused within
that method.

Andreas Molzer f80f4a06d5 Make the Unknown field optional 
Several other uses that currently rely on num-traits for conversion have
no Unknown representation. Thus, the converter now outputs only known
variants or an error and the exposing function then can put the error
value into an Unknown variant instead.
