Configure encoder options - compression level

[dbernheisel]

Scenario: I have a bunch of video that I want to pack into a zip file. Typically with video, the files are already compressed, so compressing again via Packmatic would be largely wasteful.

It looks like the Encoder is hardcoded to use deflate with compression :default and I'd like to set this to 0 so it's just storage and speed up.

I'll be happy to submit a patch that can include the compression level as an Encoder.option that passes it to deflateInit, or whatever you prefer. Let me know. I'm using Packmatic.build_stream with a list of streams provided to it, so I'm hoping to give it Packmatic.build_stream(streams, compression_level: 0).

Just checking in! I'm planning on submitting a PR within the next week or two so I can relieve some CPU on my servers.
