Implement a large and comprehensive set of math delimiters

[topological-modular-forms]

Problem. LaTeX comes with multiple delimiters, such as \big, \bigg, \Big, etc., but often these are not enough, with some math expressions being just tall enough to require parentheses bigger than \big(...\big) but smaller than \Big(...\Big).

An example of this feature being requested is given in TeXSE 483976, and I've found multiple instances of this happening in my own work.

Design Plan. To this end, I plan to design an extensive set of math delimiters that will account for such cases.
