Error parsing TypeScript checks - baseVisitor[type] is not a function

[clample]

Some TypeScript checks can trigger the following error:

17:25:14 › npx checkly test add_private_location.spec.ts
    Error: Encountered an error parsing check files for 
    add_private_location.spec.ts.

    The following files couldn't be parsed:
        PrivateLocationPom.ts - baseVisitor[type] is not a function

After some initial investigation, it looks like this is related to acorn-walk: acornjs/acorn#829. We likely need to add handlers for all of the TypeScript specific AST nodes.
