feat(function): add allowedInArgument instead of greediness property (#2134)

Browse Source 
* Remove `greediness` property

Use boolean `grouped` property instead, which is more consistent with 
LaTeX.

BREAKING CHANGE: \cfrac, \color, \textcolor, \colorbox, \fcolorbox are 
no longer grouped.

* Rename grouped to allowedInArgument

* Reenable tests

* Update documentation

* Fix typo

## Macro arguments
Tokens will not be expanded while parsing a macro argument. For example, `\frac\foo\foo`,
where the `\foo` is defined as `12`, will be parsed as `\frac{12}{12}`, not

## `\newline` and `\cr`
`\newline` and `\cr` no longer takes an optional size argument. To specify vertical
spacing, `\\` should be used.
## `\cfrac`, `\color`, `\textcolor`, `\colorbox`, `\fcolorbox`
They are no longer allowed as an argument to primitive commands, such as `\sqrt`
(without the optional argument) and super/subscript. For example,
`\sqrt\textcolor{red}{x}` no longer works and should be changed to
`\sqrt{\textcolor{red}{x}}`.
