I am posting this PR as a draft so that Manuel Reis and others

can work with it. I will revise this PR description later.

### Notes:
1. It does not yet run on github actions without errors.
2. It appears to have no memory leaks
3. It has problems with the testing infrastructure that I am working on.
4. CMake does not work for testing v3_nczarr_test because of CMake Policy
   [CMP002](https://cmake.org/cmake/help/latest/policy/CMP0002.html).
5. Ubuntu + Automake appears to work including testing v3_nczarr_test.
6. make distcheck does not work because of difficulties with VPATH.
