Determine pixel type and chip number for ITK

Adding code to determine the pixel type (normal, long, or big) and chip number for ITK quad modules. This will be needed for getting the calibration constants from the conditions DB, which I have working with a local database copy. For the moment, however, useCondDB is still set to false in job option so the new code is not used yet. Indeed, RunUpgradeTests gives all tests passed, no change in output, as expected. Since changes are within an if(isITK) there won't be any effect on non-ITK reconstruction either
