Draft: Resolve "Make a first validation test on the basis of radio-emission simulation"

Closes #520

The point of this MR is to gather some scripts that perform some kind of validation when we either push new code, or do it in a more standard fashion like once per month for instance so we don't waste a lot of resources every time we push something. I already have scripts that are testing important quantities coming from radio. But since at the moment the radio branch is not merged yet, they can't really be used. In any case though, we need to decide on specific quantities that are independent from shower to shower fluctuations and set a limit to the errors we accept for these quantities.
