Replace the term "ordinate" by "coordinate" for conformance with ISO 19111 terminology. The ISO standard said:
In this document, a coordinate is one of n scalar values that define the position of a single point. In other contexts, the term ordinate is used for a single value and coordinate for multiple ordinates. Such usage is not part of this document.
SIS was using ordinate, but OGC/ISO standards consistently use coordinate instead. We should align on international standard usage.
This change implies the following incompatible changes:
- In org.apache.sis.geometry.DirectPosition1D, public field ordinate is renamed coordinate.
- Serialization UUID of DirectPosition1D and ArrayEnvelope changed.
