Implement download script and more

Related to management#37 (closed)

@cbenz @bduye Could you please do a quick review of this code?

Be careful TOP_CATEGORIES are defined in dares_settings.py

When asserting, prefer giving details that a nice user message.

I would do:

assert(len(TOP_CATEGORIES) == TOP_CATEGORIES_NB), [TOP_CATEGORIES, TOP_CATEGORIES_NB]

because imagine you're reading a GitLab CI log, when it fails, you can see the actual values.

Here is my review.

Do not take them as requirements, I let you judge about what to do or not given the time it takes

Here is an additional general recommendation: try to make commit messages starting with a verb and being a short sentence (read more if you'd like here.

Now I'm going to try to execute the download script.

Thanks!

I executed the script dares_to_dbnomics.py.

Without using the --push option, it made a commit in the source data repository, but also pushed it to GitLab. Can you fix it?

You can make the 2 scripts executable, to homogenize with the other fetchers.
