Install struphy on clusters

[max-models]

• Added private runners on TOK, Raven, Viper, and Pitagora.
• Add script for loading the recommended module files for each cluster
• Add CI job which installs the code on each cluster
• Only run the CI job in a weekly scheduled pipeline (?)

The .github/scripts/install_and_test.sh script is executed only on the private runners, it installs, compiles and tests struphy. It can be executed manually too and should work on Raven/Viper/TOK/Pitagora

To simplify the installation on the clusters, I've added the following bash files in setup/:

• modules.pitagora.sh
• modules.raven.sh
• modules.tok.sh
• modules.viper.sh
• modules.sh

The modules.MACHINE contain the variables MODULES_INTEL and MODULES_GCC which lists the modules needed for intel/gcc on the current machine.

The modules.sh detects which machine we are on, and helps you load or show the modules needed.

# Usage:
#   ./modules.sh [load|display]
#     load    - Loads the required modules for the detected system/compiler
#     display - Prints the module load command for the detected system/compiler

So for example, if you want to load the GCC modules (which is default), you just type:

source ./setup/modules.sh load
# or
source ./setup/modules.sh load gcc

To load the intel modules, you type:

source ./setup/modules.sh load intel
