Proposed change

Adds OGC logos for the SensorThings integration.

Type of change

• Add a new logo or icon for a new core integration
• Add a missing icon or logo for an existing core integration
• Add a new logo or icon for a custom integration (custom component)
  • I've opened up a PR for my custom integration on the Home Assistant
    Python wheels repository
• Replace an existing icon or logo with a higher quality version
• Removing an icon or logo

Additional information

"SensorThings" is a standard designed by the Open Geospatial Consortium (AKA "OGC"). Info about the standard at https://ogcapi.ogc.org/sensorthings/ . The logo is a downscaled version of the SVG available at https://www.ogc.org/about-ogc/policies/media-guidance/ .

This has been done during the joint OGC-OSGeo-ASF codesprint - opengeospatial/developer-events#46
