\verb not parsed correctly

[vanatteveldt]

Latex \verb allows inline verbatim using a custom delimiter, e.g. \verb+code+ renders the word code as a verbatim. TexSoup does not seem to deal with this, seeing the whole argument as part of the next text node:

>>> TexSoup.TexSoup("A \\verb+code+ example").all
[A , \verb, |literal| example]
>>> TexSoup.TexSoup("A \\verb|literal| example").all[1].name
'verb'
>>> TexSoup.TexSoup("A \\verb|literal| example").all[1].args
[]
>>> TexSoup.TexSoup("A \\verb|literal| example").all[2].text
['|literal| example']

It also tries to parse the contents of the verbatim, causing an error if it contains e.g. a dollar sign:

>>> list(TexSoup.TexSoup("A \\verb|df$col| column").all)
