Precise length checking in `decode_slice`

[marshallpierce]

It would be good to have the length error only emitted when we know it to be required.

Any chance this gets fixed?

What's going on with pull #227? Is it stalled? It seems like it fixes a lot of issues. Let me know if I should start fresh or continue from that pull request.

I don't know the status. Presumably the author got busy with real life, etc. Small PRs are more likely to be reviewed and merged promptly since they require smaller blocks of time to review.

Note that this is appears to be a regression. Code used to work fine with base64 0.13 now returns an incorrect OutputSliceTooSmall error under 0.21.

Hm, that's not good. I'll see if I can find time to address this myself.
