django-bootstrap-icons (last release July 2024) only read the SVG of
each {% bs_icon %} from static/icon_cache; for an icon not there it
fetched the SVG from a CDN while rendering the page, and it brought
defusedxml along. A 20-line template tag in webvirtcloud reads the
same files; the package, its CDN path and the BS_ICONS_CACHE setting
go. requests stays: websockify needs it.
