Add OpenOrdersAccount functionality

A new class OpenBookOpenOrdersAccount has been added to retrieve OpenOrdersAccount information. An additional method to OpenBookManager enables fetching this account data. Furthermore, a corresponding unit test has been added to validate this new functionality. Unrelated to these changes, developer organization details have been removed from pom.xml.
