Manim-onlinetex

Breaking Changes
- Update package to account for changes in [`manim`](https://github.com/ManimCommunity/manim); more specifically, changes brought on by https://github.com/ManimCommunity/manim/pull/2476.
- NOTE: This makes v0.2.0 of `manim-onlinetex` incompatible with versions of `manim` older than v0.15.0.

Bugfixes
- Fix a bug where `tex_template._texcode_for_environment` is called unnecessarily.

This release fixes a bug where an `HTTPError` is thrown if `LatexCluster` has served up a `502 Bad Gateway` error.

This release marks the replacement of the usage of [LaTeX4Technics](https://www.latex4technics.com/) in favour of [LaTeXCluster](https://www.latexcluster.org/). This was done because LaTeXCluster explicitly stated that the API was publicly available.

A note on limitations of the add-on has been added. TL;DR : Don't clear your `Tex` directory too frequently so you don't over-strain the APIs.

Nothing facing the end user has changed; the same steps as usual should be followed when using the add-on.

The very first release of `manim-onlinetex`.
You can get it from `PyPI` like so:

bash
pip install manim-onlinetex


and use it like so:

py
from manim import *
from manim-onlinetex import *


Note that you should always import the plugin _after_ you import the main library. This is to ensure that the plugin properly replaces the parts of the main library that it should.
