v1.1.1 fails with export specifier in string

[bluwy]

In v1.1.1, es-module-lexer errors when parsing these valid JS code:

export default "export default a"

export default "export default 'a'"

export default "export function foo() {}"

export default "export function foo() {return bar}"

Here's a stackblitz repro, installing v1.1.0 instead fixes the issue. From the patterns, it looks like it's parsing the export specifier within the string.

Stumbled upon this in Vite: vitejs/vite#12036

Thanks for reporting, fix in #149.
