ARROW-81: [Format] Augment dictionary encoding metadata to accommodate additional use cases cc @julienledem @nongli @jacques-n. I am hoping to close the loop on our discussion in https://issues.apache.org/jira/browse/ARROW-81. In my applications, I need the flexibility to transmit: * Dictionaries encoded in signed integers smaller than int32. For example, with 10 dictionary values, we may send int8 indices * Indicator that the dictionary is ordered These features are needed for Python and R support, and in general for statistical computing applications. Author: Wes McKinney <wes.mckinney@twosigma.com> Closes #297 from wesm/ARROW-81 and squashes the following commits: c960bac [Wes McKinney] Augment dictionary encoding metadata to accommodate additional use cases
