Protection improvements for SimpleAvatarProtection, eye tracking and microphone reliability improvements, other bugfixes

Tweaks:

- Added extra protections for the SimpleAvatarProtection, preventing extracting of meshes and materials in most cases
-- This still isn't designed to offer 100 % protection within Neos, but makes it significantly more difficult to extract the data. The license/object ID system will offer protection at asset level once implemented

Bugfixes:

- Fixed EquipTooltip, GetTooltip and DequipTooltip nodes not working correctly (reported by @Parker and @Vigilabo)
- Fixed GetTooltip and DequipTooltip throwing an exception when the node is set to Unknown
- Fixed default snap distances being affected by the model scale when importing model as snappable (reported by @Medra)
- Fixed Vive Pro Eye tracking breaking when the headset is briefly disconnected, especially with wireless (reported by @Reactant and @FustyLugs)
-- Let me know if this fixes the issue completely. I'm pretty sure it should, but I don't have wireless to test
- Added audio input (microphone) reinitialization when the audio data stops coming (e.g. when the device is unplugged or wireless connection is lost, reported by @Reactant)
