Cleanup PR

[aaravpandya]

This PR does the following

1. Cover the export sizes of the observations behind static asserts so that they are always correct and cannot be incorrectly set.
2. Introduce collision behaviour params
3. Set up hooks for testing on every merge.

The scope of the PR has increased due to various correlated things that were hard to separate out. In addition to the above, the following changes are also implemented.

1. Ignore collisions for certain types of entities
2. Refactor the Map object location from init.hpp to types.hpp to reuse EntityType enum. This way we can reduce the repetition caused by MapObjectType and MapRoadType, maintain consistency and track types globally
3. The types are now specified in more detail to facilitate collision ignorance.
4. The behaviour of the agents on collision can now be controlled by a new enum in the params -

    enum class CollisionBehaviour: uint32_t
    {
        AgentStop,
        AgentRemoved,
        Ignore
    };
