colorbar_position not working in 3.2.0

[alaniwi]

colorbar_position is broken (for some use cases at least) in 3.2.0

Test case:

data file test.nc attached (<1MB, but in a zip file because GitHub doesn't allow attaching .nc directly): test.nc.zip

Broken example (paths redacted in error message):

>>> import cf
>>> cf.__version__
'3.14.1'
>>> import cfplot as cfp
>>> cfp.__version__
'3.2.0'
>>> f=cf.read('test.nc')[1]
>>> f
<CF Field: eastward_wind(time(1), pressure(1), latitude(160), longitude(320)) m s**-1>
>>> cfp.con(f, colorbar_position=[0.1, 0.1, 0.8, 0.02])
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/path/to/cfplot/cfplot.py", line 1029, in con
    cbar(labels=cbar_labels, orientation=cb_orient, position=colorbar_position,
  File "/path/to/cfplot/cfplot.py", line 8256, in cbar
    colorbar = matplotlib.colorbar.ColorbarBase(ax1, cmap=cmap,
UnboundLocalError: local variable 'ax1' referenced before assignment

Working example (same code, earlier cfplot version - also a different cf version but guessing that this is unimportant):

>>> import cf
>>> cf.__version__
'3.13.0'
>>> import cfplot as cfp
>>> cfp.__version__
'3.1.23'
>>> f=cf.read('test.nc')[1]
>>> f
<CF Field: eastward_wind(time(1), pressure(1), latitude(160), longitude(320)) m s**-1>
>>> cfp.con(f, colorbar_position=[0.1, 0.1, 0.8, 0.02])
>>> 

produces:

Thanks for the bug report. I had rewritten the cf-plot cbar routine somewhat and had a indent too far for the code related to the position option. This is fixed in cf-plot 3.2.7
