GEOSGeometry: Add WKB support

Attached is a patch that adds WKB support to the GEOSGeometry object, which we can use for more efficient conversions/access.

Create a GEOSGeometry by passing the binary data as a buffer type (via buffer()):

# wkb = buffer('\x01\x01\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\x00\xf0?')
# geom = GEOSGeometry(wkb)
# geom.wkt
'POINT (0.0000000000000000 1.0000000000000000)'

Get the WKB out:

# geom = Point(0, 1)
# geom.wkb
<read-only buffer for 0x2b10ff1c2030, size -1, offset 0 at 0x2b10ff1a6d18>
# str(geom.wkb)

In addition to tests for WKB, I've added a number of extra tests around geometry creation from formats other than WKT.
