Updated the Gradle wrapper to version 8.8, enabling support for Java versions up to 23.

Use coordinates [0, 1] instead of [-1, 1].

The parameter velocityHalfLife is replaced with a new friction coefficient which is normalized for 60 fps.

New ensureTypes() method ensures that all particles have a type that is within the matrix size.

• represent friction by specifying the velocity's half life period (previously, you had to specify the decay after 1s, which was less intuitive)

higher and more stable performance due to usage of a thread pool
