full latex support

[daslu]

At the moment, you can have LaTeX in markdown, and it will work if you render through Quarto. https://scicloj.github.io/clay/#markdown

Here, markdown means both comments (;;) and kind/md.

But when kind/md is nested in other kinds (e.g., kind/hiccup or kind/table) it will not work at the moment, since it goes through a different rendering pathway.

The support in direct HTML (when not rendering through Quarto) was dropped at some point. We should eventually bring it back.

Updating the description above: kind/md does work (in Quarto) when nested inside kind/table.

The other limitations still hold.
