Add support for mono repo

[prabirshrestha]

Add suport for monorepo option such that it includes packages folder where one can add multiple packages.

pnpm is giving me problems in the monorepo, like not detecting some dependencies @tamagui/button inside Tamagui dependency.

The monorepo works with Yarn.

Anyone successfully monorepo'd with Bun?

@isaachinman yes though we only have one other package but we are not having a problem, there was an issue with duplicate react-navigation packages which we have a canary fixing right now by moving it to a peerDependency, should be out today fully if that's an issue you see.
