Bug: Wrong Data Type for Spatial Serialisation

[no1melman]

surrealdb.net/SurrealDb.Net/Internals/Cbor/Converters/Spatial/GeographyPointConverter.cs

Lines 44 to 49 in 53e2c57

	writer.WriteBeginArray(2);
	writer.WriteString(value.Longitude.ToString());
	writer.WriteString(value.Latitude.ToString());
	writer.WriteEndArray(2);

Here there are two strings being written, instead it should be two decimals being written.

I had to debug into the Http Engine to see the bad request coming back from the server complaining about needing an array with two decimals. I was getting some random red herring about cbor needing a map(5) or something.
