Enhance pysa datetimes processing (#50)

[biligonzales]

Describe the changes

Adding some logics into pysa.py to try to process the datetime better. Also, exception handling has been added to avoid crash of the script.

How was it tested?

Before: scrapping failed at some point if pysa was defined in the yaml config file (see related issue).

Now:

• [x] scrapping works
• [x] dates look good (although as we don't know what is the true value, we can only admit it's relevant)
• [x] the script does not crash any longer because of the try/catch instructions.
