Coordinate parsing should allow spaces inside parentheses

[brettle]

The output should not be empty in test11():

RobotCode2018/Robot2018/test/org/usfirst/frc/team199/Robot2018/ParseScriptFileTest.java

Line 150 in 089009a

assertEquals(true, output.get("CLRx").isEmpty());

Ditto for test13().

Most importantly, "(4, 20)" should be allowed since putting a space after a comma in a common convention and would be a particularly common mistake.

This is a significantly harder thing to do, since you can't just string.split(" "). I'll implement it later, but it isn't priority for now.

I'm pretty sure this is a one line fix that doesn't involve a call to split().
