fix: Remove altitude support when reading geo URI

Browse Source 
Please note that altitude is not yet supported as [RFC 5870](https://datatracker.ietf.org/doc/html/rfc5870) requires altitude to be othrometric, or height above the WGS-84 reference geoid. Support for geoid offset is discussed more in https://github.com/barbeau/gpstest/issues/296 and https://github.com/barbeau/gpstest/issues/530.
