PR for new qmpy version V1.5 - last upgrade before cloud transitioning

[tachyontraveler]

Final version upgrade before cloud transitioning

1. Github Actions
   1. Ditched Travis CI completely and moved on to GH Actions
   2. Regular qmpy tests and Docker container builds (dev and deploy) are tested
   3. Currently limiting to CI. But CD will be added once the GCP project is initialized and set up
2. Template Dockerfiles for dev and deploy are added to a new directory dockerfiles
   1. Docker images are currently at a size of ~1.5 GB.
   2. Since the .env environment files are easily customizable, these docker containers can be used for dev and production without any (known) security risks.
3. Pre-commit enabled
   1. Hook for Black formatting
4. Python upgrade from v3.7 to v3.9
   1. avoided Python 3.10 only due to unconfirmed support for some of the dependent packages in v3.10
5. Upgraded JSMOL package (most of the file changes are due to this commit). No significant changes other than copy-pasting the new JSMOL files
6. Differentiating production and main packages based on an environment variable - instead of keeping two branches with mostly the same scripts
   1. The main differences between main and production are at the frontend - especially at the computation-related data access. This is not handled by an environment variable.
   2. WSGI data are not included in qmpy anyway.
7. OPTIMADE v2.0 - related modifications to REST API
