geography/gama: Update to 2.22

This is a bug fix release.

  New gama-local adjustment XML output definition
  gama-local-adjustment.xsd version 1.02.

  New XML tag <not-applicable/> was added to the adjustment ouput
  format for cases with zero degrees of freedom, where the standard
  deviation test is not applicable (previously there were only two
  tags <passed/> and <failed/>).  Old XML output files are formally
  complient with the new XSD version 1.02
