v0.8.4

Fixed

• Improved how the <LMarker> decides when not to render the default icon, resolving an additional issue surfaced in #266 Vue-leaflet LPopup does not update with prop change.
• Reinstated use of the Leaflet global L by default, unintentionally removed in 1bb4a71, resolving #260 Geoman integration with Vue3 Leaflet.
