imagemin-cli — update to v.3

[Roy Revelt]

We're using
"imagemin-cli": "^2.1.0",
but v.3 is the latest: https://github.com/imagemin/imagemin-cli

It looks like there was a breaking change, -o flag is now required.
Double-check, but I think:
"imagemin": "imagemin src/images dist/images -p",
should be changed to:
"imagemin": "imagemin src/images -o dist/images",

I also removed -p as there's no plugins to override. Once I did that, everything started to work fine again after update.

I tested this but needed to make a small change to the path to get it working. I ran imagemin src/images/* -o dist/images and all appeared well.
