Spaces in labels should convert to dashes

[ntjess]

The following latex document contains valid labels:

\documentclass{article}
\begin{document}
\section{Test section}\label{my label}

In section \ref{my label}, ...

\end{document}

However, typst doesn't allow spaces in labels. Compiling the output results in:

error: unclosed label

A similar problem occurs with slashes (an occurrence for auto-generated biblatex entries):

\cite{10.1117/12.695309}

But since pandoc can't change the citekey, perhaps this should be a warning?
