Add CLIs for running operations

[jnh5y]

@dr-jts This looks like fun, so I wanted to try it out.

I think the testbuilderop.sh needs to reference JTSTestBuilder.jar instead of JTSTestRunner.jar.
(E.g., the last line should be...)
java -cp ${JTS_LIB_DIR}/JTSTestBuilder.jar org.locationtech.jtstest.testbuilder.cmd.TestBuilderOpCmd $@

Separate from that, can you give a quick example of using the new command line tool?

[dr-jts]

Right, that reference to JTSTestRunner.jar is a copy-paste bug. I'll fix it very shortly

[dr-jts]

An example of running is:

testbuilderop -op Overly.unaryUnion -afile some-file-with-geom.wkt -output wkb

That reads the WKT file (containing one or more geometries), executes the Overlay.unaryUnion operation (which is just a synonym for Geometry.union() in this case), and outputs the result as WKB.

One slightly confusing thing is that the -op arg has to be Category.function, which are listed in the TestBuilder Spatial Function panel tree view.

If Category is omitted, Geometry is assumed. But only some Geometry methods are actually given under the Geometry category. So that might be bit confusing. I think I'll add all the Geometry methods there, so that it's more obvious. I will also add a dump of the full list of function names that are available (triggered by a -help argument).

Thx for testing this out - let me know how it goes.
