LaTeX sending and rendering support

[array-in-a-matrix]

Describe the problem

Cinny 2.X.X had unintentional support for sending and rendering messages containing LaTeX using markdown. The typescript rewrite has removed the side effect.

Describe the solution you'd like

It would be nice if offical LaTeX support was added as other clients have experimental support.

looks like the msc to officially support latex markup is in fcp now, may be a good time to revisit this? (https://github.com/matrix-org/matrix-spec-proposals/pull/2191) edit: has now been merged
