Add function to get a group of modules based on a json path

[fraqe]

Hello,

I added this function to get modules from any type of manifest structure, as it is not always a flat one.

Initially I did this to simplify the use of Create React App with Craft CMS, but it’s not limited to this particular case: with this modification we can get any file from the manifest, whatever its structure (as long it’s a valid json)

For example, considering this manifest:

{
    "style.css": "css/style.sfkjsf734ashf.css",
    "app.js": "js/app.gldlkg983ajhs8s.js"
    "editor": [
      "css/editor/index.css",
      "js/editor/index.js",
      "plugins": [
        "js/editor/plugins/importbmp.js",
        "js/editor/plugins/export.js",
      ]
    ],
    "store": [
      "preview": "js/store/preview.js",
      "standalone": [
        "js/store/index.js",
        "js/store/chat.js",
      ]
    ]
}

It is now possible to get the content of the editor group like this: {{ craft.twigpack.getModuleTagsByPath("$.editor.plugins") }} or we can simply get a single file: {{ craft.twigpack.getModuleTagsByPath("$.store.preview") }}

Because underhood it use the JsonPath specification, so any path type is supported, imho it adds a lot of flexibility to this great plugin.

Let me know what you think about it.

Ah I'm sorry I missed this PR somehow @fraqe -- on the surface, I like the idea. My concern is testing, but I'll have a look!

No problem, for the moment I use my forked version and it meets my needs. If this PR can be useful to other people and needs a little more work to be merged, let me know.

I'm going to want to revisit this as a part of supporting Vite and the different manifest.json they support.
