Add max/min validation for latitude / longitudes
There are a few platform status messages which have come through in hydrogen with a latitude of 178 which I think should have failed validation.
And update example messages with valid coordinates. All the example platform status messages have a latitude of 178.1 which is not a valid latitude.
"properties": {
"latitude": {
"type": "number",
"minimum": -90,
"maximum": 90
},
"longitude": {
"type": "number",
"minimum": -180,
"maximum": 180
}
}
