ORC file reader support

**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**

Be able to support reading [ORC file format](https://orc.apache.org/) into Arrow arrays

**Describe the solution you'd like**

New crate named `arrow-orc` or `orc` to support reading ORC.

**Describe alternatives you've considered**

**Additional context**

TODO: flesh out the steps needed, e.g. support statistics, indexes, compound datatypes, async

Start by reading the ORC format documentation and defining whether the new crate should be named arrow-orc or orc. Map the required scope for reading ORC into Arrow arrays, including statistics, indexes, compound datatypes, and async support. Done means the agreed reader scope is implemented and ORC data can be converted into Arrow arrays.
