 Strangely, trying to read any Geometry, apart from a Point, with Z, M or
 ZM coordinates from WKB always fails with a message such as:

 "ParseException: Unknown WKB type 234"

 An example of such geometry is the following:

 LINESTRING Z (0 1 2, 1 2 3, 2 3 4)

 Its (hex) WKB representation is:

 01ea030000030000000000000000000000000000000000f03f0000000000000040000000000000f03f00000000000000400000000000000840000000000000004000000000000008400000000000001040

 This WKB is correct, and PostGIS and others handle it properly.

 I will post a pull request on GitHub with failing tests, and put the link
 here.
