[PATCH yew-widget-toolkit-assets v3 1/1] charts: add necessary classes for Map

[Dominik Csapak <d.csapak@proxmox.com>]

these classes are used by the new Map<T> widget.

The map contains several widget that need some styling:
* map info: we need to set the z-index and reset transition in case this
  is set somewhere.

* the map itself: needs to disable touch actions and set it's width and
  height to 100%

* the map-location: is a circle with a color specified via the
  'pwt-location-color' variable (so it's easier to set in a nested
  element)

* the interaction-panel: is placed on the top right

* the location-pulse: a small animation that represents loading and
  highlights a selected element.
