• Docs: https://docs.rs/oxipng/5.0.1/oxipng/enum.Headers.html

• Test: https://github.com/shssoichiro/oxipng/blob/7ffbe1fb7865a8e97512e63cef06bebc245059a1/tests/flags.rs#L224-L230

• safe would remove all auxiliary data blocks that do not potentially affect the rendering of the image. For example, Text Chunks will be removed.

• all would maintain the current behavior and remove all auxiliary data blocks.

	strip: opt
	.strip
	.map(|s| {
	if s {
	oxipng::Headers::All
	} else {
	oxipng::Headers::None
	}
	})

imageoptim uses safe by default.
