Provide deflate native module?

[jonnor]

For decompression support, this library relies on the deflate module being available. And for compression, the deflate library must additionally have been built with compression enabled - which is not the default on even the bigger port configurations like ESP32 or Unix.

However, it seems that there is a native module available for deflate - at https://github.com/micropython/micropython/blob/master/examples/natmod/deflate/deflate.c
So it would seem to be possible to build that into .mpy modules that can be installed at runtime, without having to rebuild and reflash a device. Ideally, this kind of downloadable module would be provided by upstream MicroPython. But as a workaround, it could be relevant to provide it here.
