Automatically retrieve difficulty labels from existing guides

[benoit74]

As of today, iFixit API is reporting guide difficulty with a label which depends on the language selected (i.e. if you browse https://pt.ifixit.com/api/2.0/guides/... the guide difficulty will be in Portugues).

To accomodate with this fact, we have created a list of difficulty labels in constants.py

ifixit/ifixit2zim/constants.py

Lines 41 to 112 in 4fe09d4

	# Open this URL in the various languages to retrieve labels below

It would be preferable to retrieve automatically this list from a pre-made list of guides (and assume we will maintain only the english version to check that the guides difficulty has not been changed since last scraping).

The configuration in constants.py would then only hold a set of difficulties with following properties:

• difficulty label in English
• ID of a guide with this difficulty
• CSS class to apply for this difficulty

The following process could be done at the scraper start:

• retrieve all guides IDs stored in config for the various difficulties in all configured languages
• check that the english version difficulty labels did not change, otherwise fail. Mention that this failure could be either because the guide difficulty has been updated - in which case we will have to find another guide with the appropriate difficulty - or because the label for this difficulty has been updated by iFixit - in which case we will have to update our configuration in constants.py
