Not working properly with TexLive 2021 and 2022

Hi,

I have been using mmacells for a while on Overleaf. However, I have to change the TexLive version to 2020 in order for it to work.

When using TexLive 2021, I get the following error:

! Undefined control sequence.
<argument> ...otalleftmargin \hbox_unpack_clear:N 
                                                  \@labels 
l.143 \begin{mmaCell}{Code}

The control sequence at the end of the top line
of your error message was never \def'ed. If you have
misspelled it (e.g., `\hobx'), type `I' and the correct
spelling (e.g., `I\hbox'). Otherwise just continue,
and I'll forget about whatever was undefined.

When using the 2022 version, there are no errors but the In[x] and Out[x] do not appear: Here's what this code prints

\begin{mmaCell}[]{Code}
    Apart[1/(s^2-1)]
\end{mmaCell}
\begin{mmaCell}{Output}
    1/(2 (-1 + s)) - 1/(2 (1 + s))
\end{mmaCell}

This should be fixed by #42, which is already merged, but not released yet. Newest mmacells.sty file from master branch should work properly.

Yes, that fixed it. Thanks!!
