@cyphar thoughts on this PR? Hoping to avoid a umoci fork. |

A fork definitely won't be necessary, I'll review this on Monday. Sorry, I was a bit busy last week. |

I'm not sure I like that we ignore invalid arguments here. If we make this act on *gzipCompressor we could make it return a bool (or error) and then the caller can decide if they care about whether WithOpt actually did anything.
Alternatively, it feels like it should be possible to reimplement all of this compressor stuff with a closure that is passed by the caller (that creates the writer and configures it). But that would require more work...

Maybe we could add a CustomCompressor just for cases where you need to configure the compression? Idk...
