Add networking for World Download Progress

[Zyro1331]

Is your feature request related to a problem? Please describe.

There are statistics that a User networks that can be accessed through ProtoFlux (Such as ping, fps, queuedPackets, etc..) I'd really like to see another value to be networked by Users, which could be the Download progress when entering a world.

Describe the solution you'd like

I would like to propose a feature which adds "Approximate World Download Progress" to these networked values, as it would make it much easier to make custom systems that utilize this.

Here's some examples:

• A Loading bar above a user to indicate that they are loading to other users, which could help with awkward interactions like someone immediately trying to show you something while you still can't see their avatar nor the world yet.
• This could be used to help improve game worlds and VR experience worlds, forcing a user to stay in a small area while they load the rest of the world to prevent spoiling the presentation for themselves.
• This could also be utilized to prevent issues with people falling through unloaded mesh colliders in some cases. (Even though most people shouldn't use Mesh colliders unless they really have to :p)

Describe alternatives you've considered

I've made a custom Loading Indicator entity that uses the SettingSync component as a proof-of-concept for what this feature could look like.

this. Please.

Was literally going to ask this on the Discord. Came across this because I wanted to feature request changing the load order, but this is probably even more essential, considering I would like to do what was suggested here, and keep new joins in a room with doors that don't open until the world is at least loaded enough they're not going to fall through floors or have some other sort of major bug...

going to fall through floors

This is actually caused by a missconfiguration of the world. There are properties in the Physical Locomotion settings of a world to prevent this from happening. I'll make a video.
