Create docker container for WSIMOD

[dalonsoa]

After #24 , it should be relatively easy to create a Dockerfile that let you run WSIMOD within a docker container. A docker-compose.yml file should also be added to simplify its local usage and testing. These files could live within a dafni subfolder in the main repository - or directly in the root folder if they are just those two.

The Dockerfile should be written such that it creates an image that, when executed, will run wsimod CLI with the relevant input arguments:

python -m wsimod --settings /data/inputs/settings.toml`

It will trust that, when run, the correct volumes are mounted in the container (namely that /data/inputs and /data/outputs are available) and that the data is available where it is supposed to be, according to the settings.toml file.

While we will do our best to make this file as general as possible, its goal its to confirm to the requirements of the DAFNI framework, so in case of doubt, it will be tailored specifically to fulfill its needs. https://docs.secure.dafni.rl.ac.uk/docs/how-to/how-to-create-a-dafni-ready-model
