Is your feature request related to a problem? Please describe

get_project_paramters returns a list of parameters, but the functions below that uses it only need an iterator to get the requested item.

https://github.com/pyrevitlabs/pyRevit/blob/develop/pyrevitlib/pyrevit/revit/db/query.py#L792-L858

Describe the solution you'd like

• add a iter_project_parameters function with the content of the current get_project_parameters but with yield instead of the list generation
• transform the get_project_partameters to return list(iter_project_parameters)
• use iter_project_parameters in the functions below

Also, model_has_parameter doesn't really return a boolean, we should add a is not None at the end of the return line.

Additional context

There might be other situations like this in the code, no need to waste memory with lists to only get one (or some) item!
