py-netCDF4: mark as not for python 2.x

This depends on numpy which does not support python 2.x.
Not sure why this doesn't break bulk builds.

Log message:
py-netCDF4: updated to 1.5.6

version 1.5.6 (tag v1.5.6rel)
=============================
* move CI/CD tests from travis/appveyor to Github Actions.
* move netCDF4 dir under src so module can be imported in source directory.
* change numpy.bool to numpy.bool_ and numpy.float to numpy.float_ (float and
  bool are deprecated in numpy 1.20)
* clean up docstrings so that they work with latest pdoc.
* update cython numpy API to remove deprecation warnings.
* Add "fromcdl" and "tocdl" Dataset methods for \ 
import/export of CDL
  via ncdump/ncgen called externally via the subprocess module.
* remove python 2.7 support.
* broadcast data (if possible)to conform to variable shape when writing to a slice

version 1.5.5.1 (tag v1.5.5.1rel)
=================================
* rebuild binary wheels for linux and OSX to link netcdf-c 4.7.4 and hdf5 1.12.0.

version 1.5.5 (tag v1.5.5rel)
=============================
* have setup.py always try use nc-config first to find paths to netcdf and
  hdf5 libraries and headers. Don't use pkg-config to find HDF5 if HDF5 env
  vars are set (or read from setup.cfg).
* Change MIT license text to standard OSI wording.

version 1.5.4 (tag v1.5.4rel)
=============================
* fix printing of variable objects for variables that end with the letter 'u'
* make sure root group has 'name' attribute.
* add the ability to pack vlen floats to integers using
  scale_factor/add_offset
* use len instead of deprecated numpy.alen
* check size on valid_range instead of using len.
* add `set_chunk_cache/get_chunk_cache` module functions to reset the
  default chunk cache sizes before opening a Dataset.
* replace use of numpy's deprecated tostring() method with tobytes()
* bump minimal numpy version to 1.9 (first version to have tobytes()).

math/blas, math/lapack: Install interchangeable BLAS system

Install the new interchangeable BLAS system created by Thomas Orgis,
currently supporting Netlib BLAS/LAPACK, OpenBLAS, cblas, lapacke, and
Apple's Accelerate.framework.  This system allows the user to select any
BLAS implementation without modifying packages or using package options, by
setting PKGSRC_BLAS_TYPES in mk.conf. See mk/blas.buildlink3.mk for details.

This commit should not alter behavior of existing packages as the system
defaults to Netlib BLAS/LAPACK, which until now has been the only supported
implementation.

Details:

Add new mk/blas.buildlink3.mk for inclusion in dependent packages
Install compatible Netlib math/blas and math/lapack packages
Update math/blas and math/lapack MAINTAINER approved by adam@
OpenBLAS, cblas, and lapacke will follow in separate commits
Update direct dependents to use mk/blas.buildlink3.mk
Perform recursive revbump
