Some Niivue options do not get properly passed to the Niivue instance

[AnthonyAndroulakis]

Currently, the Niivue widget (python) can get initialized with a set of options.
On the typescript side, Niivue first gets initialized with 0 inputs, and then the Niivue options are modified after.
Even though updateGLVolume is called after each option modification, some options still do not get modified correctly.

@AnthonyAndroulakis , could you give some instructions to replicate this behaviour (maybe using a specific option that is not getting set properly) so that I can test locally on my machine?

It turns out I was not initializing the Niivue object correctly. I should initialize Niivue with its options rather than initializing with 0 options and then modifying the options.
