Lack of .dbf in test cases

[joshday]

I just realized all but one of the cases in test/shapelib_testcases do not have a .dbf file. Given .dbf is mandatory according to the ESRI spec, we should add those.

In my quick search of http://shapelib.maptools.org/ I didn't see where those test cases are taken from.

It may be so long ago they are gone now. @yeesian do you remember the source of the test cases here?

Yeah sorry I don't fully remember what I did back then to generate them by now. A search on google turned this up: https://github.com/OSGeo/shapelib/blob/6189dbd83ba2382fe0ebbc8f2308e582832c93fa/shptest.c#L238-L275

From what I read in /test/shapelib_testcases/readme.txt, I think I generated them from running shptest.c in http://download.osgeo.org/shapelib/shapelib-1.3.0.tar.gz (archive of the other versions at http://download.osgeo.org/shapelib/).

Possibly we should introduce new ones for https://github.com/GeospatialPython/pyshp/tree/b65a2b76968c5fe7698c3f7ea0c429e81a5f870a/shapefiles/test (discussion in #40 (comment))
