Ported manim-voiceover (A manim CE plugin) to work with manimgl

What is manim-voiceover

So, if you haven't heard about manim-voiceover which is a plugin for manim CE. It basically let's you record your voiceover directly on the command line. The benefit is that you can sync your audio to animations using bookmarks, it uses python's with block to so do. And during development, you can use something like gtts and later record your own audio once you are done. It also generates subtitle for the video. Check out its official page for more information.

Why am I bothering you with this post?

I made a shift from using manim CE to manimgl and so I brought this manim-voiceover with me. Forked it and made changes for it to work with manimgl rather than manim CE.

What am I proposing?

Right now I am using it as a local pip install, but if we decide to make it live, I will do some code cleanup etc and publish it on pip as manimgl-voiceover. Will also need to do a small change in manimlib's scene_file_writer.py to be able to write a subtitle file (with timing).

P.S. - I don't have experience with working on open-source projects and releasing them. So will try to learn as I go. Feel free to point out any mistakes or misdirection you see.

I should probably add this too -

During development of your animations, you will be working as usual. With opengl window. So all the benefits of opengl and the good stuff.
Then I write to file with using gtts to validate the voiceover and timings with respect to the animations.
Then I change the config to use recorder and when I run the command with write to file, it will ask to record my audio.

This seems to duplicate an earlier announcement I made yesterday: #2383
To avoid splitting the discussion, let's continue there.
