Some not green skills are mapped to green ESCO skills

[lizgzil]

Not an issue - but wanted to write one to keep a log.

I noticed something weird in the "new green skills" - some of the none-green skills (as given in the ENTS column) were in the green ESCO list!

I realised this has occurred because an entity was classified as not green, but then the closest ESCO skill (full taxonomy) it mapped to was a green one.

So I think we are still right to not say these are green skills (by trusting the classifier) but we need to be careful to remove these green-ESCO skills from the analysis of "new green skills".

this only effects 9162/13185204 of all the skills ever - so really isn't a big deal in other parts of the analysis. But it does cause problems in the new green skills.
