Typescript parsing issue with @ symbol in docstring

[johncsnyder]

With this example.d.ts:

/**
 * Some documentation
 *
 * @see https://example.org
 */
type Foo = string;

Running flowgen ./example.d.ts I get the following

(node:16376) ExperimentalWarning: The fs.promises API is experimental

    ts.SyntaxKind[type.kind]: JSDocNameReference

Removing the @see from the docstring fixes the issue.
