Alpine linux support

[solshark]

Hi,

Trying to install under Alpine linux (docker):

Downloading binary from https://github.com/xiangshouding/node-pngquant-native/releases/download/v2.0.1/linux_musl-x64-57_binding.node
Cannot download "https://github.com/xiangshouding/node-pngquant-native/releases/download/v2.0.1/linux_musl-x64-57_binding.node":

Is it possible to solve?

更新的时候@xiangshouding ，
cnpm install -g fis3
到最后一步了，发现这个文件找不到
`[3/3] scripts.install fis-optimizer-png-compressor@0.2.0 › node-pngquant-native@2.0.1 run "node ./scripts/install.js"

HTTP error 404 Not Found

Hint: If github.com is not accessible in your location
try setting a proxy via HTTP_PROXY, e.g.

  export HTTP_PROXY=http://example.com:1234

or configure npm proxy via

  npm config set proxy http://example.com:8080

It has nothing to do with proxy. Basically build for alpine not available.
