Introduces Occlusion masks table and related endpoints

[fe51]

TO REVIEW AFTER #531 (introducing poses)

This PR to address #524  which is part of the planned changes to the data model

It introduces the following modifications

• Add table occlusion_masks in model
• Add occlusion_masks schema & crud
• Add occlusion_masks CRUD endpoint
• Updates poses endpoints adding occlusion mask listing related to a pose
• Update tests
• Update db diagram

note

• occlusion mask read endpoint is permissive endpoint on (as long as authentified on the api)

What is missing (to be discussed of to handle in another PR)

• Alembic migrations
• Client updates -> will be done later
• Client tests (struggled to be properly run locally)

Happy to discuss it

it might be a good idea to test with more than one mask
