Resolve compiler errors due to rank mismatches

[G-Ragghianti]

Work in progress to resolve compiler complaints:

Error: Rank mismatch between actual argument at (1) and actual argument at (2) (scalar and rank-1)

by promoting some scalars to single element arrays.

Hi @G-Ragghianti, what you are doing looks good to me, I see that you have this as WIP, so let us know when you think you are done and we can review. Julien.

[G-Ragghianti]

It was mainly a WIP because I was wanting to also include updated in TESTING/LIN/*, but that has a different problem that will be more difficult to resolve. I think this is ready to go.

@langou I forgot that I also attempted to resolve a problem in the github workflow due to a missing blas/lapack provider. My first attempt didn't work, so let's see if I can get that working or remove the changes in main.yml.

[G-Ragghianti]

I've added sudo to install openblas0 in the workflow runner. Let's see if the workflow can run now.

@langou Can you approve the CI checks to run for this PR?

[mgates3]

@G-Ragghianti It looks like there are merge conflicts on make.yml.

[langou]

The conflict in the make.yml is

<<<<<<< gragghia/implicit_func
    - name: Install OpenBLAS
      run: |
        sudo apt-get update
        sudo apt-get -y install libopenblas0
=======
    - name: Install BLAS and LAPACK
      run: sudo apt -y install libblas-dev liblapack-dev
>>>>>>> master

We have an issue with

mpif90 -O3 -o xspblas1tst psblas1tst.o psblastst.o slamch.o pblastst.o PB_Cwarn.o PB_Cabort.o ../../libscalapack.a -llapack -lblas
/usr/bin/ld: cannot find -llapack: No such file or directory
/usr/bin/ld: cannot find -lblas: No such file or directory

And I merged #141 to try to fix this.

I will resolve the conflicts and get this through the CI again.

OKey doc great. #141 seems to do the trick. Good.
Thanks @hughcars for #141
