Enum Parameter Overrides

[georgerennie]

Is your feature request related to a problem? Please describe.
Some designs (e.g. ibex top level) can be parameterised at the top level by enums, but the -G option to set top level parameters currently does not seem to support setting these parameters to enum values, as in the following example:

package my_pkg;
typedef enum integer {
	Case0 = 0,
	Case1 = 1
} param_e;
endpackage

module top import my_pkg::*; #(parameter param_e param = Case0);
endmodule

slang test.sv -G param=my_pkg::Case1

This errors with 'param=my_pkg::Case1' is not a valid form of parameter override.

Describe the solution you'd like
The -G param=my_pkg::Case1 syntax (or equivalent) to be supported to set top level parameters.

Sure, that seems reasonable.
