add regex exceptions to swallowing

[Soliprem]

Personally, I went with the following:

    swallow_exception_regex=^(nvim|v|vi|wev|R)\b.*$

under "misc" (where you also set swallow_regex)

This line makes it so windows spawned by nvim (such as pdf for latex or typst compilers), wev windows and R windows won't swallow the terminal. (v and vi are just there because I have them as nvim aliases. This can be changed as you prefer
