Implement noise map transformation & normalization

[tomrijnbeek]

🆙 Improvement proposal

#221 implements noise maps, but these noise maps have only limited functionality, as they can only generate [0, 1) values along a square grid. In practice, you almost always want to combine different noise maps, transform the noise map values using a function (generally to create more structure in your otherwise very arbitrary noise). It should be possible to things such as:

• Resize your noise map dimensions (e.g. normalize it to the 0-1 coordinate range).
• Apply transformations on the noise value (e.g. change the amplitude of your noise function).
• Add different noise functions together (e.g. add them, take their maximum, etc.)
