The Vologram material is not created correctly on Android if empty

The Unlit/Texture shader is not correctly applied at runtime to the Vologram material when no material is assigned in the MeshRenderer.

It works well in the Unity Editor, but shows a lit (maybe standard) material when building the app to an Android device.

If I create myself an Unlit/Texture material and apply it to the MeshRenderer the Vologram shows the correct appearance.

[BUG] >2GB Volograms not Loading

Describe the bug
From Discord:

Hey guys, Im trying to enable the placement of a vologram within my scene based off of the AR Foundation tracked Image Manager. If the image is detected then the vologram should be placed etc... so basically image based detection. I seem to be having an issue though, Im not sure if saving a vologram object as a prefab to be placed is supported, but when the trigger is detected the vologram dosnt seem to appear? An object is definitely being placed within the scene as the vologram audio is playing etc, but its as if the mesh of the vologram just dosn't appear

To Reproduce
Steps to reproduce the behavior:

1. Create a prefab containing the VolPlayer component
2. Write a script that adds the prefab to the scene
3. Build the scene and run on an Android device
4. The vologram is placed but it is not visible

Expected behavior
Following the steps above, the vologram should be visible

UPM Support

Please make this a UPM package! 3rd party code doesn't really belong in Assets any more. It just clutters up our repositories with and complicates deployment and installation.

[Platforms] Oculus Quest 1 headset

From reporter:
"We have tested the latest version of the unity package of your Volograms player (0.11.1).

We have the problem of displaying the Volograms player on the Oculus Quest (1 or 2) :

Under the Unity project we can test the Volograms player on the development PC (in the Unity application, in the interface proposed by the development tool): as soon as we install the apk on the Oculus Quest (1 or 2), the volograms player is not displayed anymore."

reduce bandwidth in vertex data upload to gpu

i need a hand here - this is the bit i referred to in the PR description. i assumed i could just not upload indices/uvs if it wasnt a keyframe but it seems to need that. perhaps there's a clear() somewhere that is resetting things.
i wanted to reduce mesh upload bandwidth - not a big deal but should be possible to get a tiny performance improvement.

VolPostBuild throws dependency error for Android project

Importing the unitypackage in an Android project throws an error with the UnityEditor.iOS.Xcode import.

Just added an #if UNITY_IOS to the whole class as a workaround.

Loop not working if "Play On Start" is unchecked

When the VolPlayer is configured but the Play On Start is not checked, and we trigger the Play method elsewhere, the Vologram plays but don't loop even if Is Looping is checked or the player.isLooping property is set to true through code.

To Reproduce
Steps to reproduce the behavior:

1. Create a VolPlayer and configure it as usual.
2. Unmark the Play On Start check, with the Is Looping check marked.
3. Call the volPlayer.Play() method.
