Updated C2D script

[nklomp]

Hi Simon,

These are updates to the Docker image and script to get everything working. It has been a bit of a struggle. It turned out to be some resource constraints on the C2D environment which caused issues. These have been addresses yesterday by our partner Delta Dao

I updated the Marketplace with the latest version and you can run and see (previous) outputs at https://www.energyshr.nl/asset/did:op:51e21e623bdca2bf72bf7b47e1b9681d5a622ace03ac0f352213eb3540a44950.

Main changes:

• Use mimetype detection because the dataset filename will be 0 in the C2D environment, so you cannot rely on file extensions
• Removed the RUN entry from the Dockerfile and adjusted the local run script to behave in the same way as the C2D environment (so it provides the entrypoint)
• Removed some nice things you did in the Dockerfile, because at this moment the C2D environment wasn't working with these. I for sure will get in contact with Delta Dao about these
