Simplified the build process to calling a pair of scons commands

[DmitriySalnikov]

I've redesigned my code and made it easier to work with it.

• Added .gdextension file.
• Added optional lipsync support.
• Added an artifact build with all the necessary files for the release. .TwoVoIP on the run's page. That is, you can simply download this file and attach it to the new release.
• Added an example in the Readme.
• I fixed the web build and added support for Godot 4.3. Unfortunately, I was able to successfully run the example only in Godot 4.3.
• I replaced the connection of Git modules with HTTPS instead of SSH. Before that, I couldn't clone the repository because I didn't have an SSH key configured.

Windows with lipsync:

Web:

Android:

As written in the readme, you now need to enter 1-3 commands to build the project.

scons apply_patches # optional to speed up the build.
# Add more arguments if necessary, for example "platform=web lipsync=yes".
# This command and the next command must have the same additional arguments.
scons build_opus # build opus using cmake. You can run it once.
scons # build this library. Then you can run only this command to update the library.

Very nice indeed :)

I'll assume it's right. I can't keep up. There's more polishing and tweaking and user-testing needed on the front end before it's ready for the assetlib. I want this add-on to shock people when it works.
