feature request: option to always show packed bundle size changes

[bartveneman]

Similar to how size-threshold allows setting to -1 to always show a diff, I'd like to get a 🎉 when my packed bundle size decreases. Perhaps setting pack-size-threshold to -1 could do this?

i think that's a good idea 👍

would be open to PRs or i can try get to it eventually!
