droute/matcher-domain: add gzip support

[honwen]

first time use rust, code review needed

Also, I am not sure if gz support is necessary, because even it seems like no one is releasing domain lists through gzip format. And in-memory decompressing still puts pressure on embedded machines like router.

Agree, it a feature for own use, https://github.com/honwen/openwrt-dnsmasq-extra/tree/master/dnsmasq-extra/files/data Or I maintain this feature in my own branch

need help for improving, refer: https://docs.rs/flate2/1.0.20/flate2/#async-io

I have supported it with the latest commit. Instead of gzip, you can write directly file: a.gz
