Build size differences

[shellscape]

Great work on this plugin 🎉

In looking through the source and reading the docs here it struck me that there might be another vector for useful information in this plugin: build size differences. Keeping track of config hashes or some other somewhat-static element and caching build sizes based on an identifier (say, in a file in a temp directory, or in the module itself) and displaying size increases or decreases, might be useful to folks.

How do you define the base size ?

I'd find something I could hash (like the config, or the set of files in the bundle) and then store the hash along with the resulting file size for a build. Then reference that hash and base value for subsequent builds that matched the hash.
