JabRef offers preview based on so called BST styles. However, currently there is no option to select them in the UI.

Things needed.

• Add the BST styles to the preview layout list
• Add an option to configure/add styles. Add a single style or configure a directory to load them from
• Test if they can be selected and rendered

Additional context
Bst files can be found in https://www.ctan.org/topic/bibtex-sty

Codewise:
PreviewTabViewModel#setValues needs to check for BstPreviewLayout
