Export not detected

⚠️ This is not real-world code. It's technically a bug, but no real program will notice it. Feel free to close this issue!

Consider this non-strict mode code: (GitHub's syntax highlighting is broken)

function fn() {
    yield / "/ //" /*
}
/*/
}

module.exports.foo = 2;

// */

The tokens are:

[function] [Identifier: fn] [paren left] [paren left] [brace left]
[Identifier: yield] [division] [String: "/ //"] [Comment: \n}\n/ ]
[brace right]

[Identifier: module] [dot] [Identifier: exports] [dot] [Identifier: foo] [equal] [Number: 2] [semicolon]

However, cjs-module-lexer returns { exports: [], reexports: [] }.

Start by running the provided non-strict JavaScript snippet through cjs-module-lexer and inspect how it tokenizes the yield, regular expression, and comment sequence. Done means the lexer detects foo in module.exports rather than returning empty exports and reexports results, with regression coverage for this input.
