Create react-native example

[sethvincent]

Demonstrate usage in react-native in preparation for mapeo-mobile implementation.

~Goals for this issue~:

• [ ] Figure out the minimum requirements to properly bundle Mapeo Core Next and any native deps it relies on to run on NodeJS Mobile
• [ ] Get a basic Mapeo Core next program working, such that data can be sent and retrieved between NodeJS Mobile and React Native

New goals for this issue:

• [ ] given the introduction of new native modules introduced in the hyper stack, figure out what builds properly and what doesn't. collect a list of these issues and possible approaches to fixing or addressing them
  • namely fs-native-extensions, udx-native

@sethvincent any ideas for what would be a minimal program to spin up mapeo-core-next in the backend process?
