build(deps): Use oxipng-pybind for PNG Compression

[ConcaveTrillion]

Replace pyoxipng with oxipng-pybind, which follows Rust oxipng v10+.
Add se.images.optimize_png() unit test.

Thanks! I'll check that test.

This package is causing Pylint to crash. Install the toolset via pipx and do:

cd /path/to/tools
pipx inject standardebooks oxipng-pybind==10.1.1.post1
pipx inject standardebooks pylint==4.0.5 pyright==1.1.408 types-requests==2.32.4.20250913 types-setuptools==80.9.0.20250822 types-lxml==2026.2.16
$HOME/.local/share/pipx/venvs/standardebooks/bin/pylint .

On my machine, this causes pylint to crash with a very long dump starting with:

/home/alex/.local/share/pipx/venvs/standardebooks/lib/python3.10/site-packages/astroid/transforms.py:123: UserWarning: Astroid was unable to transform Raise(exc=<Call l.190 at 0x7f7813bdb040>,
      cause=None).
Some functionality will be missing unless the system recursion limit is lifted.

If I uninject your package, it works again.

It appears to be a known Astroid bug for when a package uses compound python annotated types. See: pylint-dev/astroid#2764 (similar issue but not exactly the same) It is fixed it Astroid 4.1.2 (https://github.com/pylint-dev/astroid/releases/tag/v4.1.2), but pylint has not updated. On my machine the recursion limit must be set higher by default, because I wasn't able to reproduce the crash, pylint completes. The easiest thing might be just to set `ignored-modules=oxipng` until pylint gets the latest astroid update. If you'd prefer, I can see if I can make the typing less strict in the module. I do all the type checking there with `basedpyright` and all linting with `ruff`. pylint seems to be falling behind compared to ruff (especially with processing speed of checks).

[ConcaveTrillion]

I rewrote the code to work around the pylint recursion bug. It's not as elegant, but it works.

I added a test in the library to exercise pylint 4.0.5 against all the exposed public API objects and verified no astroid warnings. If you bump the dependency to 10.1.1.post2 the recursion bug should go away.

Great, that fixed it, thanks!
