It is [][16]float32.

You can write it using modeler.WriteAccessor:

modeler.WriteAccessor(doc, gltf.TargetArrayBuffer, data)

Note that data must be [][4][4]float32, not [][16]float32.

I've added a helper to read/write inverseBindMatrices in #92.

I'm not completely sure, but it seems that you can't specify a target for inverseBindMatrix.
glTF-Validator says there is an error.

When I output glTF, an ACCESSOR_INVALID_IBM error occurred, and just deleting the target of the bufferView made it work normally.
