Example table metadata:
```json
                ""license_frequency"": {
                    ""units"": {
                        ""frequency"": ""Hz"",
                        ""channel_width"": ""Hz"",
                        ""height"": ""m"",
                        ""antenna_height"": ""m"",
                        ""azimuth"": ""degrees""
                    }
                }
```

This works surprisingly well! I'd like to add support for using units when querying but this is PR is pretty usable as-is.

(Pint doesn't seem to support decibels though - it thinks they're decibytes - which is an annoying omission.)
