Developer: Plot firefighter location on the dashboard

[krook]

This feature should be embedded in the version deployed for the February burn. It should also be updated to fit the look and feel of the long-term dashboard in #80

Current work is in the dashboard folder.

It could also benefit from an existing UI library, like Carbon.

If using LPWan or GSM network connectivity many carriers have the ability to geolocate connected devices using the network rather than a GPS module

For the developers tasks, would it be helpful to use an existing product like IBM's IoC for Emergency Services? https://www.ibm.com/au-en/marketplace/emergency-management
