Labels missing or need modifying in measurePSF

[raacampbell]

• Bruno and Mark found there are no labels to measure PSF when saved as PDF. Including the X and Y. There should be.
• See the inner two plots. They aren't labelled if there is no calibrated x/y? They should be labeled anyway.

My screenshot in the GUI looks like this:

There are FWHM labels as expected.

Indeed with Bruno's noisier bead there are no labels.

Aha:

>> Copying PSF fit to base work space as variable "PSFstats"
>> PSFstats

PSFstats = 

  struct with fields:

          fitStats: [1x1 struct]
          PSFstack: [51x51x80 double]
    micsPerPixelXY: NaN   <---
     micsPerPixelZ: NaN   <---
    figureSnapshot: [900x900x3 uint8]

It's been re-saved in ImageJ and the pixel sizes are missing:

>> tmp=imfinfo('~/Downloads/PSF_2020-53-28_15-02-54_00001.tif')
>> tmp(1).ImageDescription

ans =

    'ImageJ=1.52i
     images=80
     slices=80
     unit=micron
     cf=0
     c0=-32768.0
     c1=1.0
     vunit=Gray Value
     loop=false
     min=33295.0
     max=33324.0
     '

Then it reports nothing because of this in the constructor:

if exist('micsPerPixelZ','var') && isnumeric(micsPerPixelZ) && isscalar(micsPerPixelZ)
      obj.micsPerPixelZ = micsPerPixelZ;
      obj.reportFWHMz=true; % THIS STOPS IT REPORTING
end

This is fine, but the user doesn't know about it. Need to change the plot labelling so it's clear what's happened.

7d5465d08d6461e9590855cf2efe67dc2d3ac886 reports to screen if no mics/pix provided for Z. Also prints to the command line whether this information is missing in XY and in Z.
