Support `\diff` from `esdiff` latex package

Is your feature request related to a problem? Please describe.
It is really annoying to write

\frac{d x}{d y}
\frac{\partial x}{\partial y}

every time I want to render derivative.
There is a latex package called esdiff
which allows to do this:

\diff{x}{y}
\partdiff{x}{y}

as an equivalent to the above.

Describe the solution you'd like
idk how mathjax uses latex, but in a standard project it'd be just adding \usepackage{esdiff}

Describe alternatives you've considered
A clear and concise description of any alternative solutions or features you've considered.

Additional context

$$
\frac{\partial x}{\partial y}
$$

Start by reading the linked esdiff package description and MathJax's existing LaTeX extension support. Check how the examples using \diff{x}{y} and \partdiff{x}{y} should render, then verify both commands produce the corresponding derivative expressions in MathJax.
