Currently, the `c-ts-mode--get-indent-style` function: 
```
(defun c-ts-mode--get-indent-style (mode)
  "Helper function to set indentation style.
MODE is either `c' or `cpp'."
  (let ((style
         (if (functionp c-ts-mode-indent-style)
             (funcall c-ts-mode-indent-style)
           (alist-get c-ts-mode-indent-style (c-ts-mode--indent-styles mode)))))
    `((,mode ,@style))))
```
We can use `c-ts-mode-indent-style` to customize our indentation.
However, the function doesn't accept a `mode` parameter, without which
we cannot determine the current customizing indentation style of what
language (c/c++).
