Using \( ... \) as opposed to $ ... $ when toggling using ts$

[danieleavitabile]

Is your feature request related to a problem? Please describe it.
When toggling between equation environments using ts$, I find the move to $ ... $ ineffective: one comes from a multiple line equation, and when toggling to inline, vimtex puts into a single line. In the vast majority of cases I have to go back to the text, and modify it or re-format it.

Describe the solution you'd like
I would like that $ ... $ be replaced by (...), or the latter be added to the toggle list. I also would like that what is within the delimiters stay as is (no equation rearranging).
