Support for gitsign's GitSigns*Cul

[73]

Hey,

do we have support for gitsign's GitSigns*Cul? I would like to span my current cursor line highlight on the whole line.

Adding a highlight_override for CursorLineSign already works for lines that do not have a symbol by gitsigns. However, marked lines do not get styles whether GitSignsAddCul, GitSignsChangeCul, or GitSignsDeleteCul are defined.

Revisited this again. Just works. So nevermind I guess.
