SOS 1.0.0 GetObservation response:
- add check for streaming data and merge streaming data because streaming data encoding is not yet implemented for this response
- add check for next values before call merging or getter methods
- Add concrete schema location to GetCapabilitiesResponseEncoder for SOS 1.0.0
- Remove not SOS 1.0.0 schema locations from getter method because this can cause that the SOS 1.0.0 schema location is missing in the responses, see #45
