* Calculates a Tibetan date for a given western date. This does a binary search, and is therefore
* much slower than tibToWestern().
*
* The algorithm could be much improved by using the reverse of meanDate() to start with,
* and then using the fact that julian dates and "tibetan day numbers" have a quasi-linear relation.
*
* @param {Date} date - the western date
* @return {Day}
