Refactor to Hook Api with backwards-compatible wrappers

[RasmusKlett]

It seems the Router moved to a new namespace in the ReasonReact update. I hope you will accept this small fix to adapt.

I've rewritten the core to use React Hooks, while keeping the old Component API, and adding .Jsx2 wrappers.
In my opinion, this is really nice to use with Hooks instead of components. Would you be interested in merging this? Some kind of response this time around would be appreciated.

I did not update the examples, as I could not get them to build. I got some error about a -color flag passed to bsb. It seemed like a rabbithole related to reason-scripts.

Who do I need to contact to get a response? @cnguy @grabbou @knowbody?

@RasmusKlett I am no longer a maintainer of this project, but it seems like it's not maintained anymore so you might be better of forking it.

Probably @grabbou will be a better person to give you a more accurate update

Ah, that's really too bad. @grabbou can you confirm this repository is dead, and that you will not take a look at my changes?
