Support for juicing entire directories

[yo-gi]

Workaround is something like this find coverage/srcbackup -name '*.html' | xargs -P 16 -I@ yarn juice @ @
but it would be great if juice had native support for doing this as I suspect it'd be faster

Similar to #337 by @staghouse

Thanks for the hint on a workaround above @yo-gi !

My version below. This takes all *.html files in src/ and then runs juice on them to put them in build/, also with a maximum of 16 processes at once:

find src -name '*.html' | xargs basename -a | xargs -P 16 -I@ juice src/@ build/@

@karlhorky in your example do both references to src need to be the actual directory path? Or would you cd there first so it's the active directory?

[karlhorky]

Both of the src references need to point to the directory where the source files are, so if you changed into the directory with cd, then you could probably use . instead. I ran it from the root of the project, so I used src in both locations.
