fix GaussianOutput bug with multiple route lines

[xjf729]

When route lines in gaussian output file like:

 ----------------------------------------------------------------------
 # B3LYP/6-311++G(2d,p) EmpiricalDispersion=GD3BJ SCRF=(SMD,READ) freq 
 opt=(loose,maxcyc=400)
 ----------------------------------------------------------------------

If we use GaussianOutput to parse route lines, route_parameters would be looked like as follows, in which, freq and opt are concatenate.

{'EmpiricalDispersion': 'GD3BJ',
  'SCRF': '(SMD,READ)',
  'freqopt': {'loose': None, 'maxcyc': '400'}}

Now, I fix the method to parse route lines, to give the right route_parameters:

{'EmpiricalDispersion': 'GD3BJ',
  'SCRF': '(SMD,READ)',
  'freq': None,
  'opt': {'loose': None, 'maxcyc': '400'}}

Could you zip the log file and load it as test_files/molecules/EC.log.gz using e.g. monty?

I have zipped test_files/molecules/EC.log to test_files/molecules/EC.log.gz and set the zopen mode in GaussianOutput to "rt" to load .gz file.

Thanks for the fix @xjf729! 👍
