[FEATURE] Allow expression functions to use named parameters This commit sets the framework for allowing expression functions to use named parameters. Ie, instead of: clamp(1,2,3) you can use: clamp( min:=1, value:=2, max:=3) This also allows arguments to be switched, eg: clamp( value:=2, max:=3, min:=1) Additionally, it allows for a more structured definition of function parameters to handle optional arguments and default values for parameters. These are currently being done using a hacky infinite argument list. I've utilised the postgres ':=' syntax for specifying named arguments to avoid potential collisions which may arise with the equality test if we re-used just the '=' operator alone.
