Rename raycasting and shapecasting methods in SpatialQuery

[Jondolf]

Objective

Currently, the following names are used for raycasting/shapecasting methods:

• cast_ray
• ray_hits
• ray_hits_callback
• cast_shape
• shape_hits
• shape_hits_callback

While these are fine, they could be improved. The distinction between cast_ray and ray_hits isn't immediately obvious from the name, and the naming isn't very consistent. In addition, a more common and perhaps cleaner name for cast_ray is raycast.

Solution

Rename the methods to be cleaner and more consistent:

• cast_ray → raycast
• ray_hits → raycast_many
• ray_hits_callback → raycast_callback
• cast_shape → shapecast
• shape_hits → shapecast_many
• shape_hits_callback → shapecast_callback

The old methods still exist, but have been deprecated and will be removed after the next release.

Migration Guide

let before = spatial.cast_ray(...);
let after = spatial.raycast(...);

let before = spatial.ray_hits(...);
let after = spatial.raycast_many(...);

let before = spatial.ray_hits_callback(...);
let after = spatial.raycast_callback(...);

let before = spatial.cast_shape(...);
let after = spatial.shapecast(...);

let before = spatial.shape_hits(...);
let after = spatial.shapecast_many(...);

let before = spatial.shape_hits_callback(...);
let after = spatial.shapecast_callback(...);
