Add support for MAGIC+LST-1 performance

I tested is against the legacy script and checked that I get the same values for Crab bin by bin.

FYI, Julian added the MAGIC+LST1 performance at high zenith (NB: derived from MC). I send you the link to the MR privately.

No it is not, but we are planning to ask MAGIC and LST EBs to release them, so that also external people can use them for evaluation, and also because like this we do not need to have a private and public version of the source simulator. So ok, we can wait for the blessings first, then think about including them here too.
