Adjust thickness values according to specification of an industrial product

[ekatef]

Changes proposed in this Pull Request

Regarding equivalent insulation thickness (l_strength in the code):

1. The thicknesses must be in fact in inches, as styrofoam is Canadian brand.
2. Our inputs for l_strength determined as 76 mm and 197 mm are in fact 3inch and 7.76 inch, respectivelly. The first value is perfectly reasonable according to Dupont product sheet, while for the second one I'd rather assume 7.5 inch = 3.5 inch + 4 inch = 190.5 mm.
3. Real insulation thickness values differ from l_strength according to the values of l_weight,

Perhaps this was meant for a different branch? Reopen if that is not the case.

I would suggest handling pull requests that do not target the master branch in a fork of PyPSA-Eur. This will make it a bit easier for me to keep an overview over what needs reviewing. Thanks!

Yeah, indeed that was intended for chp_cc. Apologies and thanks a lot for checking @fneum!

Agree that it feels weird to work from branches instead of fork. We'll try to figure out a better way.

Thanks @fneum for flagging, this is more of a hirstoric ... diverge ... not sure. For future project we will definitely work on a fork, however, some of the features would be also nice to have also in PyPSA-Eur master branch. But we will most likely open smaller PRs and then delete this branch, or something like that

Not saying anything against contributions to the master! That is most welcome!
