Check for range_max is missing

[moooeeeep]

After the minimum range is checked here, the point is dropped when the value is smaller than range_min_.

Another check should be performed to also skip readings beyond the maximum range (threshold determined by the parameter range_max).

Example:

[...]
else if  (range > range_max_) {
    NODELET_DEBUG("rejected for range %f above maximum value %f. Point: (%f, %f, %f)", range, range_max_, *iter_x, *iter_y, *iter_z);
    continue;
}
[...]

Unfortunately I can't make a PR right now. Maybe I will get to that later.

Thanks for the report!
