Support passing zlibOptions and brotliOptions

[SystemDisc]

#106

This does not include tests or a benchmark - just wanted to quickly throw together a first-step in the direction of completing this issue: #106

This also does not include documentation, simple example is as follows:

  server.register(fastifyCompress, {
    brotliOptions: {
      params: {
        [zlib.constants.BROTLI_PARAM_MODE]: zlib.constants.BROTLI_MODE_TEXT, // useful for APIs that primarily return text
        [zlib.constants.BROTLI_PARAM_QUALITY]: 4, // default is 11, max is 11, min is 0
      },
    },
    zlibOptions: {
      level: 9, // default is 9, max is 9, min is 0
    }
  });

This is great, thanks! Can you add the tests and docs?

I will try to when I have time! I just wanted to get it started, so at least there's something to go off of in case someone else has more time. I'm currently working upwards of 90 hours per week. I just happen to be using this library, and saw this issue when I ran into a weird problem with Brotli compression. I disabled Brotli in the project I'm working on because it's not necessary. I wish I had more time to contribute. I love the open-source community. Great stuff!

Ouch, I'm sorry for your 90 hours. Thanks for the contribution!

hi there! I can take a swing at adding docs and tests, if that's alright.

@chasingSublimity go for it! 👍

Ok, here's a first pass. I'm new to Fastify, TypeScript, and zlib so happy to make any improvements you all suggest.

Does someone want to run benchmarks, just in case?

[mcollina]

Not needed here, thanks for checking!
