fix sharing arbitrary files in the session

[zodiepupper]

i initially wrote up a concept where when you would upload a file, it would embed the bytes of that file onto the object in the scene. but this, obviously, creates a TON of memory overhead.

i wanna figure out a way to dynamically allow clients to put files into the scene and use the webrtc connection to transfer the file directly.

for this, we will likely need to create a tmp file for every arbitrary file that's uploaded and then when another user goes to export it, it checks if the importing user is still present, then asks their computer to send the file bytes.

alternatively, we could make it so when a user drags a file into a scene when a matrix room is selected, it uploads the file to that room in a hidden message (or visible, just not sure how annoying it will be) and then the other user can download it like any other matrix media object.

i updated this a lil bit ago. it's still not perfect but files that don't eat all the system ram can be imported and the file byte data gets appended to the Node metadata. i have a git stash where i started working on the ref to pull it directly from the uploading client for large files. i want to put it on it's own webrtc data channel so it doesn't block main thread.

this will be fixed in the sweep for the multiplayer update. but i'll leave it open as a reminder to myself that my old method for this is shit.

i'm wondering if we could optionally sync directly to disk in the tmp directory in a way that isn't going to incriminate someone by simply being in a session. so like maybe using the end to end encryption to store the file, or even a locally defined encryption key
