Rework ors_params() #1
Description
ors_params() is still a bit fragile and fails to catch a lot of more 'special' parameters before they go to the API. Also it's a real pain to debug and generally feels very floaty.
One option would be to simply send each parameter into a switch() call and define their assertions right there instead of relying on a hard-to-change and generally very limited dataframe. This is less DRY, but it is certainly more explicit. It is also necessary to find out how to deal with nested parameters.
It is also questionable whether it is useful to export ors_params() as it really only makes sense when information is available about both input dataset and requested profile.
