Support passing test case parameter in smtc

Summary

This is not a bug, but a feature request. If there is another queue that I should create this in, please let me know.

I have a test case that takes a parameter. When I start the test case using smtc, I want to be able to pass the value of the parameter.

Steps and/or TTCN-3 code to reproduce

Create a test case that takes a parameter. Start the test case with smtc.

What is the current bug behavior?

(again, not a bug) smtc does not allow taking test case parameter.

What is the expected correct behavior?

I want to use smtc to pass the test case parameter.

Relevant logs and/or screenshots

(Paste any relevant logs - please use code blocks (```) to format console output, logs, and code, as it's very hard to read otherwise.)
