* add `workflow_dispatch` for manual running
* add `fail-fast` false in matrix
* specify `persist-credentials: false` for actions/checkout
* update actions to the latest versions
* move cache before installing the toolchain
* cache more stuff
* limit deploy to shssoichiro/oxipng repository
* reindent
* Make dependency on `image` optional
After PR https://github.com/shssoichiro/oxipng/pull/481 was merged, the
`image` dependency became unused when building with debug assertions
disabled, as it is only used to implement output sanity checks when such
assertions are enabled.
The `image` crate transitively pulls a significant amount of
dependencies, so it's useful for OxiPNG users to get rid of them when
not needed.
[Cargo does not allow specifying dependencies that are only pulled when
debug assertions are
enabled](https://github.com/rust-lang/cargo/issues/7634), so the next
best way to give users some flexibility is to gate those debug
assertions behind a feature flag.
These changes add a `sanity-checks` feature flag that controls whether
the `image` crate and the related sanity checks are compiled in. This
feature is enabled by default to keep debug builds useful to catch
problems during development.
* Fix Clippy lints
* Run tests with new sanity-checks feature enabled
* 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:

* 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.
* Build more release binaries
Include a static Linux binary with musl and a macOS build. Also add
readme, license and changelog to the release archives.
Fixes GH-134
* Merge windows and linux builds
* Test musl and darwin targets
* Fix matrix exclude key
