Add Geography __eq__ object equality?

[jorisvandenbossche]

Currently two different but equal objects are not "equal":

In [14]: import spherely

In [15]: p1 = spherely.Point(2, 2)

In [16]: p2 = spherely.Point(2, 2)

In [17]: p1 == p2
Out[17]: False

If this is still a relevant issue, I would like to give this a shot!

[jorisvandenbossche]

This is certainly still relevant!

I assume that we would want to do the same as the equals predicate (i.e. using s2geography::s2_intersects)
