Missing fast path for small integers #13

It seems that this repo has already diverged from the C code, at least for the following improvement: https://github.com/abolz/ryu/commit/c3c5641b7ea0a553d9902328659ba1df85a24992

I deleted d2s_buffered_n in f02fa5f4eed38b2e18e7de8101fbfeb097a07c45 so that improvement is in code that is no longer included in the Rust version. It looks like the improvement is specific to the way that their formatting handles small integers in exponential notation like 1E4, so it is not useful for our formatting which would be 10000.
