Size optimize int formatting

Let's use the new feature flag!

This uses a simpler algorithm to format integers.
It is slower, but also smaller.
It also saves having to import the 200 byte rodata lookup table.

In a test of mine this saves ~300 bytes total of a cortex-m binary that does integer formatting.
For a 16KB device, that's almost 2%.

Note though that for opt-level 3 the text size actually grows by 116 bytes.
Still a win in total. I'm not sure why the generated code is bigger than the more fancy algo. Maybe the smaller algo lends itself more to inlining and duplicating?
