move sui-oracle move package to public repo (MystenLabs#12922)

## Description 

Sui Oracle is a general purpose oracle that can be used to fetch data
from external sources and feed it to the Sui Chain.
It is designed to be modular and extensible, so that it can be easily
extended to support new data sources and new data types.

## Test Plan 

Move test + manual integration tests

## TODOs
We need to add more documentation to explain the design of this package
and turn it into an example.
