Angular brackets incorrectly escaped in embedded Latex

[jforberg]

Obsidian allows us to embed Latex formulae in our markdown.

Some *text* blah, also $x < y$

Obsidian-export incorrectly escapes the angular bracket between the $$ so the output document will be

Some *text* blah, also $x \< y$

But \< is not a Latex command, so this will fail when it is processed later by some Latex-aware program.

$-segments should probably be copied directly into the output, without attempting to interpret them as markdown code.
