BREAKING: feat: integer position support + numpy return + decode/encode functions + normals

[william-silversmith]

Neuroglancer multiresolution meshes require integer position attributes. Here we add numpy as a dependency and automatically detect if a numpy array is integer or float.

• Supports integer position encoding
• Radically simplifies encode/decode into functions of the same name
• Adds normal decoding support based on v0.0.18 | Supports Texture Coordinates and Normals #17 (Thanks @farunurisonmez!)

Compiling on all platforms, killed redundant jobs.
