Is it possible to set a relative limit?

[tniezurawski]

I'm wondering if I could fail the action if the file size increases e.g. by 10% or 100kB. Does such an option exist? If not, could you guide me on where to start? I can prepare the PR and documentation.

Use case:
We're far away from the limit we've set but I'd like to discourage big changes in the team as well as detect obvious mistakes where for example a huge dependency lands in the main bundle. It won't trigger alarms on the limit because we are way below it but the relative size limit would already catch it.
