add ujson

created an issue

hello,

is there any reason why ujson is not added yet? tried it out with the benchmark script and it seems to be very fast:

    i've wanted to add it, but I'm not sure how to do so in a good way. the issue is that ujson uses a different approach to error handling than the other implementations. were most implementations raise exceptions, ujson returns empty content and similar. That's a reasonable approach, but it means you could write a program that relies on anyjson that fails when using ujson, but not when using other implementations. (or the other way around). Any opinions on a reasonable way to deal with this would be most appreciated!

    Well, ujson now almost the same with the standard json module. So just adding a line ("ujson", "dumps", TypeError, "loads", ValueError, "load"), in _modules variable, it should work.
