Expose more APIs to Bedrock add-ons

The current APIs for Bedrock add-ons allows an add-on to interact only with the world, but it cannot do anything with anything else. I saw someone asking to expose a rendering API, but I would like more :

- Network API (not only HTTP, but also raw TCP/UDP, with the possibility to listen)

- Audio API (playback and recording, very useful to stream music, add voice sensitivity for Skulk sensors, or implement voice chat, with the possibility to control other sources like music or ambient sounds)

- HUD API (being able to add elements on the HUD)

*Of course*, add-ons willing to use these capabilities must declare it in their manifest, and it would be shown to the user like so :

"Do you want to install this add-on? It will be able to :

- Control audio - Record audio - Add elements to the HUD

- Access network (HTTP requests)

- Listen for incoming network requests (TCP)"

Adding those would for sure make Bedrock add-ons a viable alternative to Java mods. Thanks for your amazing work, keep going! ;)
