Add code to copy instance methods from original original class defini…

Copy all callable attributes from the parameters instance to the Pydantic model that eventually replaces the parameters instance as QualibrationNode.parameters

@maxim-v4s I can't run the formatting-checking code locally, but clearly see that what I wrote didn't make it happy. In addition to reviewing, could you please reformat and see that tests pass? Thanks

@deanpoulos just to confirm, this should work even if the custom class is defined in a script, and it should work both when you run it locally and through the FE?

@maxim-v4s some context for this PR: @deanpoulos want to add methods to a NodeParameters subclass. It seems that these methods aren't being copied, likely during the loading of the Parameters object

[maxim-v4s]

@nulinspiratie @deanpoulos
Should we copy staticmethods or classmethods? Or only instance level?
Should we copy methods of base classes?

@deanpoulos it seems that this PR introduces some breaking changes, specifically in situations where the original NodeParameters have required parameters (without a default value). In that case, loading a serialized object can raise an error.
I discussed this with @maxim-v4s, and agreed that a different strategy is probably needed. Specifically, loading should use the class of the passed parameter instance. This will be a more involved change. Let's discuss what the timeline should be for this feature

@nulinspiratie I'm glad you picked up on some breaking changes. Since I don't know the ins-and-outs of QUAlibrate, and how difficult an alternative implementation would be, can I leave this to you to prioritize? Even if it goes to the bottom of the list, it's OK.
