implement psse data checking default option

[ipssdev3]

In addition to topology checking, below are some data checking used by PSSE.

@ipssdev3 now we can pass a external data checker function to be called after the initialization process.

	  LoadflowAlgorithm algo = CoreObjectFactory.createLoadflowAlgorithm(net);
	  algo.loadflow(aclfNet -> {
	  	// here we pass a function to do the external data check after the
	  	// initialization process.
	  });

Since this a PSS/E specific feature, the actual external data checker logic is located in the plugin project.

    package org.interpss.plugin.aclf;
    
    public class PSSEExternalDataChecker implements Consumer<BaseAclfNetwork<?,?>>{
       ...
    }

See a relevant test case ExternalDataCheckerTest

@ipssdev3 The band concept is quite confusion. Can you find some actual examples?

// 1.5 Voltage Small Voltage Band BAND<0.02
// 1.6 Voltage Large Voltage Band BAND>0.02
// 1.8 MW or Mvar Small Flow Band Band<5.0
// 1.9 MW or Mvar Large Flow Band Band>5.0
