2.x.x request decompression, response compression middleware (#10)

* Comment everything out, sort Package.swift

* HBRequestDecompressionMiddleware

* Request decompression middleware

* ResponseCompressionMiddleware

* Renaming, moving code about

* Response compression headers

* Added configuration to middleware

* Remove old files

* Verify compression window sizes

* Update CI

* Use compress-nio 1.2.1

* Use deflate in some of the tests

* Update README

* Changes from PR comments

* Throw badRequest on corrupt data

* Add another bad data test

* Print error to logger when inflate/deflate init/finish fails

It should never fail, but if it does we have some output

* Fix test, we need to check contentEncoding header

-// larger than 32768 bytes otherwise run it on the eventloop
-app.addResponseCompression(execute: .onThreadPool(threshold: 32768))

-Adding request decompression means when a request comes in with header `content-encoding` set to `gzip` or `deflate` the server will attempt to decompress the request body. Adding response compression means when a request comes in with header `accept-encoding` set to `gzip` or `deflate` the server will compression the response body.
