Summary

Thumbhash generation requires raw pixel RGB data, which is not easily available from JS, but we can easily get it in native code. Created an expo module for that purpose.
Basically copy-pasted the aes-crypto module.

Test Plan

generateThumbHash("foo").then(console.log) prints "unimplemented" on iOS and Android
