significant digits?

[cainlevy]

I would like to specify a maximum number of significant digits for a number, so that I may better estimate how much space to allocate in design. Currently I may only specify precision and control decimals.

Currently:

• millify(123456, {precision: 2}) returns 123.45K

Proposed:

• millify(123456, {digits: 3}) returns 123K
• millify(1234, {digits: 3}) returns 1.23K.

I'm willing to work on a patch if this is in scope for millify.

@cainlevy I think we need that, this library has an option for it. Going for it for the time being.
