Allow round(num) to take a "number of digits" argument

[Kaedenn]

A scarpet implementation would be something like
round(num) -> round(num, 0);
round(num, places) -> (offset = 10^places; round(num*offset)/offset);

I'm finding myself needing this function more often than I expected and so I wrote roundp(num, places) to accomplish this.

That's available in the default math library (built into Carpet), you can import it placing

import('math', '_round');

at the top of your script and then call it using _round(num, precision). (precision being 10, 100, 0.1, 0.001, etc)

Wait, there are standard libraries?

Yes, there's math (few distance utils) and shapes (getting block positions for a given shape with given properties). You can find their code in the repo here (the ones with the .scl extension).

Those should probably be documented though...
