* Fix building without zopfli
* Update and optimize dependencies
These changes update the dependencies to their latest versions, fixing
some known issues that prevented doing so in the first place.
In addition, the direct dependency on byteorder was dropped in favor
of stdlib functions that have been stabilized for some time in Rust, and
the transitive dependency on chrono, pulled by stderrlog, was also
dropped, which had been affected by security issues and improperly
maintained in the past:

- https://www.reddit.com/r/rust/comments/ts84n4/chrono_or_time_03/
* Run rustfmt
* Bump MSRV to 1.56.1
Updating to this patch version should not be cumbersome for end-users,
and it is required by a transitive dependency.
* Bump MSRV to 1.57.0
os_str_bytes requires it.
* Improve performance consistency
Switch from HashMap / HashSet to IndexMap / IndexSet for consistent iteration order of various options and, as a result, more predictable performance.
* Fix verbose message
* No cloning when restoring original data
* Make reductions return a new uncompressed image
Partially fixes#145
* Async reduction evaluator
* Assert
* Faster bit depth check
* Also try 4-bit depth for small-depth images
* Skip test when using miniz
* Ensure palette is trimmed after depth reduction
Fixes#159
* Fudge factor for reductions to prefer better reductions even if gzip estimation says otherwise
* Move reductions to a module. Make copy instead of changing in-place.
* Alpha reductions
* Immutable color reductions
* Immutable interlace reductions
* Compress alpha with strategy sensitive to repetitions
* Update reductions flag when alpha changed
* Avoid needlessly cloning out-of-date idat_data and temp raw_data
