* 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://github.com/cardoe/stderrlog-rs/issues/31
- 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.
* Add initial support for changing Zopfli iterations
PR https://github.com/shssoichiro/oxipng/pull/445 did some dependency
updates, which included using the latest zopfli version. The latest
version of this crate exposes new options in its API that allow users to
choose the desired number of Zopfli compression iterations, which
may greatly affect execution time. In fact, other optimizers such as
zopflipng dynamically select this number depending on the input file
size (see: https://github.com/shssoichiro/oxipng/issues/414).
As a first step towards making OxiPNG deal with Zopfli better, let's add
the necessary options for libraries to be able to choose the number of
iterations. This number is still fixed to 15 as before when using the
CLI.
