Implement Variable-size Binary View Layout

Implement read and write of the [Variable-size Binary View Layout](https://arrow.apache.org/docs/format/Columnar.html#variable-size-binary-view-layout) and verify against integration tests.

Start with the Apache Arrow Variable-size Binary View Layout specification linked in the issue, then inspect the existing read and write implementations and integration-test setup in arrow-erlang. The work is done when both reading and writing support this layout and the integration tests verify the behavior.
