PTAL.
I changed to not forward to the internal json library. This makes it slower, but
at least the code that is visible is actually used. Otherwise users should/would
use JSON.decode directly.

LGTM.

I think having parse/stringify use the local library is perfectly fine. It
should be equivalent to using the optimized versions in dart:convert, except
possibly slower, but using the library is the right thing to do. Anything else
would be confusing.
