Should we pull in the no-longer-maintained asset-size-reporter dependency?

@mansona was browsing in here today and noticed that one of our dependencies (https://github.com/mainmatter/asset-size-reporter) is currently archived and unmaintained. Should we consider pulling that into this repo?

Yea that's probably a good idea @acorncom 👍 we also can make it a bit simpler too, since I'm using a bit of a hack to get it to "return" a JSON (you'll see what I mean if you look at where it's being used)
