Custom primitives example (#13795) 
# Objective

- Add a new example showcasing how to add custom primitives and what you
can do with them.

## Solution

- Added a new example `custom_primitives` with a 2D heart shape
primitive highlighting
  - `Bounded2d` by implementing and visualising bounding shapes,
  - `Measured2d` by implementing it,
  - `Meshable` to show the shape on the screen
- The example also includes an `Extrusion<Heart>` implementing
  - `Measured3d`,
  - `Bounded3d` using the `BoundedExtrusion` trait and
  - meshing using the `Extrudable` trait.

## Additional information

Here are two images of the heart and its extrusion:
