      Description

      While converting datasetPtc to an IsrCalib, a toTable method was added. After creating a second Table (astropy) in that method, fromTable seems to fail to read it (it read the first table fine). This was seen when trying to open a FITS file with more than one table (i.e., at least 3 HDUs) with readFits (parent class: calibType).

          Example to reproduce:

          import lsst.ip.isr as ipIsr
          		 
          inFromText = ipIsr.CrosstalkCalib.readText("/project/czw/dataDirs/obs_decam_data/decam/crosstalk/n4/1970-01-01T00:00:00.yaml")
          		 
          inFromText.interChip
          		 
          # {'N5': array([[0.00e+00, 6.69e-05],
          		 
          #       [0.00e+00, 0.00e+00]])}
          		 
          inFromText.writeFits("/project/czw/tmp/cc.fits")
          		 
          inFromFits = ipIsr.CrosstalkCalib.readFits("/project/czw/tmp/cc.fits")
          		 
          inFromFits.interChip is None
          		 
          # True

          It looks like I originally added an error inside the try block, causing it to always except before trying to read the second extension.  This update also ensures that we loop over the extensions, so there should be no limit anymore.

          Reasonably quick fix.
