create source package for NCL

[alaniwi]

Currently packaging NCL by wrapping binaries distributed by NCAR. Attempt to create a SRPM which does a genuine compilation of the source. Problems with this in the past, so low priority.

Also request from a user - if this is done - to include ESMF.

Some instructions supplied via a sysadmin at Leeds:

these are my notes for adding esmf to the ncl 6.2.0 install. it doesn't
look like i explicitly set the compiler anywhere, i think it picks this
up from:

build_config/Linux.gfortran.default/build_rules.mk

within the esmf source directory.

i don't believe this has to be installed within the ncl directories,
that was just where it seemed to make sense to put the software on our
systems - the esmf executables can be anywhere in your PATH.

# change '/path/to/ncl/install/dir' and 'netcdf library flags' as required.

Considerations added re ESMF in #40 apply here too: do not include ESMF executables, but add a dependency instead.

NCL is now available on Jaspy.
