feat: Custom tooltips and independent color filters

[AlanRynne]

Fixes #16, #17

• New ColorBy input used exclusively for applying color filters (Object data is now named Tooltip Data and is used for tooltips :point_down:
• New custom tooltips, where even the prop name is customisable. This also allows to apply data to the tooltip that is not stored in Speckle

Connecting any of the 2 (ObjectData or ColorBy inputs) will result in highlighting being active.
