Audio ThroatSFX

- Model 2 has been added, with 894 sound files. Yes, you read that correctly! Eight hundred ninety-four individually adjusted samples. The sounds are separated into three intensity categories plus a folder for gasps and slurps, meant to be used when the mouth goes away from the penis.
- Added more options for audiobundles for both models. I figured people would also want to use mixed versions of the intensities, for example low + medium, medium + high, or all intensities combined.
- Changed the folder placement for audiobundles, so things can break if you created a scene using the previous version of ThroatSFX_AB. The standard version should be fine. To fix it, you just have to load the audiobundle from the new folder location.
- Improved the demo scene with the option to showcase both voice models, and more gradual intensities (1-5). Also fixed the apparent bug in which clicking the intensities sometimes would not update the sound library correctly.

Remember when I said Model 1 was finalized? Well, I lied. I thought it would be cool for the female to gasp for air when she stops sucking. Now you have an additional folder which is "Gasps for air" inside the folder for Model 1, with 88 sounds. The intention is to use it as an End Action of LipTrigger or MouthTrigger to make an Atom moan/breathe when going away from the penis.
In addition to that, I've now made available two versions of ThroatSFX, the normal one with the loose sound files, and the audiobundle version, with the name of ThroatSFX_AB. Huuuuge thanks to @Shadow Venom for creating Audio CUA Studio, which made it possible for people like me to not have a hard time going through Unity. There's no "better" version to choose, depends on what you're after. The benefits of the audiobundle is that you have much faster loading times and you can simply add one file with everything to your scene. The downside is that you have less control of which specific sounds you want played, and also less possibilities for customization.
To show the new stuff, I've created a new basic demo scene, which was adapted from the hub's current version of Aurore's scene. THAT scene will receive a bunch of upgrades in the future, so I thought I could create a simpler version of it for people to try things out.

For now, I'll be working on adding Model 2 for the next patch.

- Removed some of the weirder sound files and added some more. Model 1 is finalized with a total of 328 sound samples.
- Reorganized the folders to add new voice models in the future, already working on theirs.
- Now sounds are separated into three intensity categories: low, medium and high. This allows a couple of things:
First, instead of a sound being picked randomly from a huge pool of sounds, you can choose a specific library of sounds depending on scene triggers and appropriate timings, for example a slower and more gentle blowjob will only trigger a low intensity throat sound, and so on. You can still choose to use like the old version, just add the three folders (low, medium and high) to the sound playlist.
Second, you can use triggers placed along the inside of the mouth which play a higher intensity sound the deeper you go. If you only hit the first trigger then a low intensity sound plays, second trigger medium intensity, and third trigger high intensity. This requires a little bit more of logic by enabling/disabling triggers as you hit them, but it's doable, and more realistic/interactive since it depends on how deep you go.
