error: could not compile `chardetng` (lib test) due to 28 previous errors

There are three kinds of errors

1. String and Vec are not imported because the crate is nostd. It's easy to import them in the tests mod
2. println! doesn't work for the same reason, but I believe that code can just be removed
3. Several of the encoding_rs functions require the alloc feature. I'm not sure how to fix those.
