Andrew Champion 71f3aa8b15 Include unknown variant for sample format 
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.

Andrew Champion a439baa948 Decoder: remove test make wrong assumption 
The byte count for strips is the compressed length. The compressed
length may be larger than the uncompressed length, especially with poor
compression choices (multi-byte samples with packbits) or small images.

Andrew Champion eadec8f0b9 Remove most unchecked size/index casts 
Convert most unchecked size/index `as` casts to checked casts with
`TryFrom`, included another top-level error variant.

This has several motivations:
- Making the library as robust as possible, including to platform
differences.
- Unchecked casts are susceptible to breakage during refactorings.
- Preparing for BigTIFF support, which will require the introduction of
generics and associated types for some parts of the de/encoders.
Unchecked primitive casts cannot be bound, while TryFrom can, and
overflowing conversions become more likely.
- Remaining u16 casts may be prone in failure in existing practice and
not just in theory during future changes.
