Closes #44
This PR add support of npy file containing
float16.Float 16-bits is not supported in JavaScript as a
TypedArray, but can be passed through javascript as an opaque memory and be used inside webgl.So what we use instead a
Uint16Array. This allow to match the right memory size and the right item indexing. This for example allow to useNdArraylibrary for slicing.In Javascript, the indexing also allow to read values as a bit field. This can be used to decode the value manually. See for example https://stackoverflow.com/a/8796597.
