Add qLogNParEGO

[Scienfitz]

Since multi-ouput is now supported we might as well add support for this alternative to qLogNEHVI

Notes:

• changed AcquisitionFunction.supports_multi_output to an explicitly set class var
• for this acqf, botorch uses an already heavily abbreviated term, so I made abbreviation identical to the original name
• the name stands for batch logarithmic noisy pareto efficient global optimization
• Botorch-latest already has an option incremental enabling to chagne qLogNParEGO's behavior in a way that sounds very similar to what sequential does. But since its not released I left that out

Here the result with the existing Pareto example indicating this basically works (the actual code change for this was not pushed):

Its also clear that this seems to be inferior to qLogNEHVI, I think this partially could come from the still missing posterior transforms

Thx, good to have this alternative 👍🏼
