Thoughts about even smaller bundle

[parzhitsky]

I had a couple of ideas to shrink the bundle even more, that are implemented in parzh/decimal.js-tiny. However, the only module system it definitely supports is CommonJS (i.e., Node.js), not sure about browsers and ES modules, haven't tried them.

Perhaps, you have thoughts about shrinking the bundle further down? If not, I can continue supporting decimal.js-tiny at my own risk.
