Expose `couch_util:decode/2` to support jiffy optionsport-json-decode-2
It can be desirable in some cases for decoded JSON to e.g. return
maps instead of the default data structure, which is not currently
possible.
This exposes a new function `couch_util:decode/2`, the second
parameter being a list of options passed to `jiffy:decode/2`.
