Reintegrate roku module dependencies into codebase

[cewert]

Is your feature request related to a problem? Please describe

Using roku modules instead of integrating the code directly creates several problems

• Jellyfin org has no access or control over the files
• The modules' code doesn't have to pass our linting/validation checks
  • Even if the modules copy our github workflows, there would still have to be some kind of plan in place to sync their workflows when we update ours.
• In order to make the modules work independently from our code base, some code had to be duplicated - see the last ~200 lines of code here.
  • There is no plan in place to update duplicated code in roku modules when original code in codebase is updated
• In order to access the modules' code you must prepend all calls with MODULEALIAS_. This makes the code slightly more difficult to read and write.
• Testing code/PRs became more complicated because one must run npm install to pull in all the necessary files for the app to work
• At the moment, we are automatically updating to the latest build/minor release during npm install without needing approval. This presents a potential security risk if the modules start pushing malicious code udpates. This one is fixable.

I can't think of one reason why having these dependencies helps us. I know there's the potential to help people who want to use the NPM modules to build a roku app but there's no reason our app has to use or depend on them. They could and should be a separate thing IMO.

Describe the solution you'd like

Remove Roku module dependencies and integrate into code base directly. There are no downsides to doing this that I'm aware of.

We also have our vscode brightscript linter and CI ignoring all code found in a roku_modules folder. This would be the only way of catching linting errors in the modules since there are no workflows enabled in the modules' repos themselves.
