Parcel 2: MozJPEG Optimizer

[devongovett]

Create the @parcel/optimizer-mozjpeg package. This should include an Optimizer plugin that compresses JPEG images with mozjpeg. Ideally, this should wrap a C++ module to call mozjpeg rather than relying on writing temporary files and calling command line tools. Perhaps such a module already exists, otherwise we should create one. If this proves too difficult, shelling out to a command line tool could be a good starting point.

This plugin should be included in @parcel/config-default for *.{jpg,jpeg} to optimize JPEGs by default in production. (??)

Configuration

Optional configuration should be done through a .mozjpegrc file. We should include good default settings, but it should be possible to override them if needed. See here for available options.

Hello,

• I just created a local plugin to do that in my own project.
• I don't have any tests.
• I don't use any configuration file.

I may have some time to help on this but I need some guidance 😉

This is implemented in the default image optimizer plugin.
