FONLL-B DIS FK table need different PTO

[felixhekhorn]

I'm sorry to say again, but NLO FK tables are still wrong (only FK tables this time though - so it's not expensive):
https://github.com/N3PDF/pineko/blob/e12c6482a32c7c8f902bfa2d2504e4bfe451fd19/src/pineko/theory.py#L325

this is wrong in the case of NLO (so PTO=1) and FONLL-B because FONLL-B also contains bits at $O(a_s^2)$ which will be neglected with this statement ...

the solution is

• find out (from the theory card) whether we're in FONLL-B
• check whether we're looking at a DIS grid (from the lumi, I guess - we can cross check with Pineappl integration with validphys nnpdf#1529)
• eventually do a correction of max_as

• if this is done - close it
• did you compare you're is_dis determination against Validphys with pineappl rebased to master nnpdf#1578 ?
• actually https://github.com/N3PDF/pineko/blob/aa1a068edffc75d8ee1a4ed8e5c44fd8630963e1/src/pineko/check.py#L87 it might be a good idea to not rely on the fact that the lepton is always the second particle in the lumi

No I haven't compared. So, before closing this, I am going to test if everything is ok and eventually I will close this.

this I can easily solve but thanks to have pointed out :)

Should we close this? @felixhekhorn @alecandido
