Specify compression ratio

[SysVR]

Is your feature request related to a problem? Please describe.
Unclear what compression ratio is being used.

Describe the solution you'd like
If this software uses oxipng, etc,
I don't know what the compression ratio is, so I would like to be able to specify the compression ratio.

Describe alternatives you've considered
Install a slider that allows you to specify the compression ratio for lossless compression.

For oxipng, Caesium uses the preset level 3, and 6 as level for libdeflater. This is a snippet from libcaesium

oxipng_options = oxipng::Options::from_preset(3);
oxipng_options.deflate = Libdeflater { compression: 6 };

Setting this levels could be something I add in an "advanced" panel.
