WIP: Initial design v2

[cserteGT3]

I needed to rethink the design of the package, which makes #1 obsolete.
The todos copied from there:

• implement evaluation for HybridProblems: 2a8a401
• separate geometries and optimization problem: 5fa9b71
• abstract type for optimization problem?
• LocalizationFeature should be a concrete type? -> yes close LocalizationFeature should be concrete type? #19
• handle machined-rough tolerances (industry "standard" says: one point, that one point should be returned) - with dc722c0 the current needs are implemented
• tests, tests, tests
• vizualization in package extension
• transition to using Meshes.Points, etc. (probably later in Transition to Meshes.jl types #6)
• API documentation
  • test API with pointcloud implementation?
  • what is exported, what is not?

This will be the way, but a bit later.

The main task or question is: how to not implement twice the tolerance and allowance evaluations. The evaluation should happen with evaluating the jump model. But I don't yet know how to do that.

[cserteGT3]

Picking up where I left it, my current goals are:

• use the JuMP model for evaluation (thus not implement everything twice)
• rethink the tolerance abstraction based on our current understanding and goals (and document it thoroughly)
• update to latest Meshes.jl
• update github CI to v2?
