[DAPHNE-#773] Undetected invalid script args

[ldirry]

When calling daphne, users can provide named script arguments that are available inside the DaphneDSL script. According to the DaphneDSL language reference, only literals may be passed as script arguments

However, the following calls of daphne with invalid script arguments all passed "successfully" (status code 0) and some didn't even indicate any error.

• Fixed invalid script arguments that try to evaulate an expression
• bin/daphne test/api/cli/scriptargs/printSingleArg.daphne foo="sin(1.23)"
• bin/daphne test/api/cli/scriptargs/printSingleArg.daphne foo="1.23*4.56"
• Fixed invalid script arguments that were not literals
• bin/daphne test/api/cli/scriptargs/printSingleArg.daphne foo=10xyz23
• Added testcases for single script arguments
• Added testcases where Daphne fails in case of an invalid script arguments
