Handle exception to show line number of parsing errors #86

Closed dgutson closed 1 year ago

Currently, when there's something wrong with the input DSL, I get this output:

 - loading workspace from DSL
com.structurizr.dsl.StructurizrDslParserException: Unexpected tokens

The important part for the user is Unexpected tokens at line 256: c4plantuml.sprite robot

I'm suggesting to handle the exception in order to show just the error part for a better user experience.
