Add Dockerfile and Docker Build Image workflow

[Giangblackk]

I added:

• Dockerfile to build geospatial Docker image currently based on mambaorg/micromamba:1.4.2 docker image. The Dockerfile simply install geospatial metapackage.
• docker-image.yml file from Github Action Docker Image build workflow

Why I did it:

• I want to have a Docker image with every popular Python geospatial packages, so I can use it for my local development environment, instead of installing from conda everytime I start new project.

Proposal:

• Using Github or Docker Hub to host built Docker image
• dynamically configure built image version and base image version.

This is my first pull request, please give more advices so I can improve it.

Thank you for the PR. It looks good to me. I would suggest removing the version pin (0.8.0). In that way, we don't need to update those files when the package version is updated. Also, the geospatial package version pin is not very useful because it always install the latest version of its dependencies no matter it is geospatial v0.7.0 or v0.8.0.

Thank you for suggestion. I will update and notify you later.

The Docker and Windows builds failed. I will fix it later.
