Update README

[ludfjig]

Updates the README to be more concise, shortens the example code, and splits prereqs into separate getting-started md. Removes the scary sounding Note: Hyperlight is a nascent project with an evolving API and no guaranteed support. Assistance is provided on a best-effort basis by the developers. in favor for less scary sounding **Status:** Hyperlight is pre-1.0. The API may change between releases, and upgrading will sometimes require code changes.

cargo hyperlight scaffold PR is still not merged so shouldn't merge this until that is merged (and released).

Removes the scary sounding Note

Are we sure we want to do this? We are not actually changing to have any stronger guarantees of support or API compatibility or whatnot right now, I think.
