Add support for >2 nested SOQL queries in SELECTS

[nwcm]

Allows higher depth of SOQL query child nesting. fixes #46

SELECT Name, 
  (SELECT Id, 
    (SELECT Id, 
      (SELECT Id, 
        (SELECT Id FROM Child4 ) 
      FROM Child3 ) 
    FROM Child2 ) 
  FROM Child1) 
FROM Parent

I had to update some of the build commands to have it correctly run. I'm not completely sure if the JAVA version is functioning

Don't see any problem, thanks for the report and the fix as well!

Needs a matching test for the JVM side but it's just a quick copy paste. I've already tried it locally and it's fine as this one demonstrates so I'll just do a quick follow up PR.
