Issue:
zrange byscore kwarg not handled
`zrangebyscore` is deprecated in redis and replace by `zrange` with a `byscore=True` argument. This isn't handled in fakeredis, and I needed to change _zrange in _fakesocket to the following to handle this case: 
```
    def _zrange(self, key, start, stop, reverse, *args):
        zset = key.value
        withscores = False
        byscore = False
        for arg in args:
            if casematch(arg, b'withscores'):
                withscores = True
            elif casematch(arg, b'byscore'):
                byscore = True
            else:
                raise SimpleError(msgs.SYNTAX_ERROR_MSG)
        if byscore:
            items = zset.irange_score(ScoreTest(start).lower_bound, ScoreTest(stop).upper_bound, reverse=reverse)
        else:
            start, stop = self._fix_range(start, stop, len(zset))
            if reverse:
                start, stop = len(zset) - stop, len(zset) - start
            items = zset.islice_score(start, stop, reverse)

        items = self._apply_withscores(items, withscores)
        return items
```
