Transform error with js file using flow type annotations

[jjblumenfeld]

When trying to run suppress-eslint-errors over a file with flow type annotations I am getting an error:

 Transformation error (Unexpected token (30:12))
SyntaxError: Unexpected token (30:12)

In this case line 30 on the referenced file looks like: import type { Route } from 'website/route.flow';

So it seems like it is throwing the error on the type import. How can I get the parser to understand the flow type syntax?

@jjblumenfeld I suspect that, as in #29, you need to explicitly specify a parser.

I'd happily accept a PR to improve the documentation if this is the case.
