escodgen is not up to date

escodegen is not up to date with the newest ECMAScript nodes, so it fails on a PrivateIdentifier AST node.

Adding

class WithPriv{
 #privateId = 1;
}

to the array_function_replacements_local_proxies.js test case from obfuscation-detection gives an error

However, overriding the version of escodegen to use in package.json like so:

    "overrides":{
      "escodegen":"npm:@javascript-obfuscator/escodegen"
  },

fixes the problem. I am trying to see if this fixes the talon_sdk.js file as well, but the file is so big that it has been running for a long time already.

While I do feel it's important to support the latest, I want to find a different package that is maintained and reputable, rather than a static fix

I haven't tried it yet but https://github.com/davidbonnet/astring looks promising and is much faster
