Parenthesis before nullsafe operator

[czuniga9]

Good day, first thanks for the awesome project!

I noticed the parser fails if you have something between parenthesis before a nullsafe operator. I found it when using code like

echo ($published_at ?? $last_modified_at)?->format('M d, Y');

but it fails even with

($published_at)?->format('M d, Y');

Here's a small example:

const engine = require("php-parser");
const parser = new engine();
const code = parser.parseEval('$a = null; echo ($a)?->format();');

And here's the output:

test/node_modules/php-parser/src/parser.js:357
    throw err;
    ^
