Jethro Kuan 023af3ec32 (feat)buffer: add customization variables for buffer (#1990) ...

This commit adds 3 custom variables:

1. org-roam-buffer-postrender-functions

This list of functions are run within the Org-roam buffer after the
Org-roam buffer is rendered. For example, one can produce latex previews
for all content within the Org-roam buffer:

(add-hook
'org-roam-buffer-postrender-functions (lambda () (org--latex-preview-region
(point-min) (point-max))))

2. org-roam-preview-function

This is the function used to extract the content to populate the buffer.
It defaults to `org-roam-preview-default-function`, which extracts all
contents within the headline up to the next headline.

3. org-roam-preview-postprocess-functions

This is a list of functions run to post-process the content retrieved
from org-roam-preview-function. It can be used to strip additional
content from the buffer, or perform sentence-unwrapping.
