Need a release process #28
Description
Need to create a release process for shapelib.
- How to handle version numbering? That last release was 1.5.0. What's next?
- Where to set the version number? Can it be done from one location? It's currently in configure.ac and CMakeList.txt
- How to manage additions to the ChangeLog?
- github action to generate rc and/or final candidate tar files
- github action to generate binaries for primary platforms
