Andreas Molzer 7cc5b98d9c Switch to Github Actions for CI checks 
More customizable, faster, more integration. We already did that for a
number of other crates with good outcome.

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.

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`.
