Columns of type double don't appear to work as key column quals?

[e-gineer]

@ellisvalentiner is trying to use columns of type double as key quals in the weatherkit plugin - https://github.com/ellisvalentiner/steampipe-plugin-weatherkit/blob/fix/lat-lng-should-be-floats/weatherkit/table_weatherkit_current_weather.go

The code looks correct, and works when the column type is string instead, but fails to see the quals when they are of type double:

> select * from weatherkit_current_weather where latitude=43.2683199 and longitude=-70.8635506;
Error: rpc error: code = Internal desc = 'Get' call for table 'weatherkit_current_weather' is missing 2 required quals: 
    column:'latitude' operator: =
    column:'longitude' operator: =
 (SQLSTATE HV000)

@e-gineer @ellisvalentiner found the issue - small bug in the FDW qual conversion code.
