Added most symbols to cmd_symbols for concealment

[superle3]

Added most symbols from mathjax's Charactermaps to the concealments.
Some symbols used in the concealments were different then the ones in mathjax.
I think the ones from mathjax are more accurate and should be used, but I can revert if need be.
I sorted it case insensitive to preserve git history somewhat but its still not a full match so the differences between
mathjax and the original are shown below.
the left object is from mathjax and the right from the current map.

edit: not all mappings work like \Subset. Not sure why
edit2: almost fixed it. unicode is not fully supported.
for example

\def\äa{hello world}`
\äa

becomes hello worlda (github markdown doesn't seem to support \def).
where as \def\aä does work normally.

But to avoid regex taking \S over \Subset for the string \Subset I added a negative lookahead for any letter (\\pu{L})
and this doesn't account for when the previous character is a special letter and the next is a normal letter.
But this already so niche that I don't think we're ever gonna encounter that.

edit3: sorted the keys by length instead. Forgot that lookahead is not supported yet on ios.
It should now fully work for every macro.

Does Mathjax have a \not symbol in their charactermaps? I ran into the lack of a conceal for it recently, and don't see it here. Could be nice to add.

Edit: guess not.

[superle3]

They do. https://github.com/mathjax/MathJax-src/blob/master/ts/input/tex/base/BaseMappings.ts
It's the last map called not_remap.

Yeah wasn't sure how to implement bug/hack free yet.

First thought was to add another variable to the conceal_maps.ts with format not\s*\\${command}, and add it to ALL_SYMBOLS
But not sure about \s*.

Also have to convert their unicode back into Tex commands but that shouldn't be a problem.

[superle3]

using not[ \t]*\\${command} instead. Obsidian doesn't like it when newlines get concealed. May come back to it, but don't think its important.

edit:
https://discuss.codemirror.net/t/preferred-way-to-create-multi-line-widget/4865/3 yeah thats not worth bothering.

[superle3]

okay I think I have tracked down all the commands that can be concealed with the current format.
I also added inf back in since #101 doesn't happen anymore,
because the next character gets checked if its not in [a-zA-Z].

Thank you for your work! I'll try to take a look soon.
