#1975: Improved CLI help page styling

- Removed the dependency on click-default-group.
- Added no_args_is_help parameter for manim render to allow easy access to help page.
- Added note to manim help page epilog on how to access other command help pages.
#2404: Add SpiralIn Animation
- Make ManimBanner to use SpiralIn.
#2534: Implement OpenGLImageMobject
#2684: Created a more accessible way to create Angles with line.py angle function - Angle.from_three_points()

#2062: Reuse shader wrappers and shader data
#2642: Migrated file_ops.py and scene_file_writer.py from os.path to Pathlib
In file_ops.py and scene_file_writer.py: Uses of str type file names have been mostly (see further information) converted to pathlib’s Path objects. Uses of os.path methods have been converted to equivalent pathlib methods.
#2655: Fix assert_is_mobject_method() when using OpenGL
#2665: Improved handling of attributes when using the .animate syntax
#2674: Document and type simple_functions.py
- Add documentation for simple_functions.py.
- Small additions with some extra clarity for these functions.
#2693: Allow using MovingCamera.auto_zoom() without animation
Allows auto zooming camera without having to play an animation by passing an animation=False argument

#2546: Fixed a file logging bug and some maintenance
#2597: Fix Bug in Uncreate with rate_func via introducing new parameter reversed to Animation
- Refractor the Uncreate. The new implementation uses a flag member reversed. Set it to True and its superclass handles the reverse.
- Introduce a bool parameter reversed to Animation. It decides whether the animation needs to be played backwards. Default to be False.
- Add conditional branches in Animation.get_sub_alpha(). If the parameter reversed is True, it would set rate_func(t) to rate_func(1 - t).
#2613: Fixed bug in Circle.point_at_angle() when the angle is not in the interval \([0, 2\pi]\)
#2634: Fix background lines drawn twice in NumberPlane
#2648: Handle user-defined centers for Wiggle animation
#2658: Fix arguments of overridden set_style for BackgroundRectangle
Using Write animation on a Text object with .add_background_rectangle() applied no longer generates a TypeError.
#2668: (Re)set background color of OpenGLRenderer when initializing scene
#2676: Fixed propagation of custom attributes in animations for the OpenGL renderer
#2688: Fixed two minor issues of SpiralIn and ManimBanner

#2630: Remove WebGL renderer
The WebGL renderer is broken and unmaintained. The support for it in Manim is removed.
#2652: Update cloup version to 0.13.0 from 0.7.0
#2678: Require backports-cached-property only for Python < 3.8
#2685: Migrate from os.path to pathlib in testing scripts
This pull request changes a number of instances of os.path to Pathlib objects and functions. In addition, this PR modifies the SVGMobject constructor to accept both a Pathlib object or a string variable pathname its constructor.
#2691: Removed CameraFrame
#2696: Made changelog generation run in parallel plus further improvements to scripts/dev_changelog.py
#2697: Sort PRs by number in changelog sections before writing
