Pull request overview
Adds Ruby-side convenience construction for variable-size binary and UTF-8 ArrowFormat arrays by allowing ArrowFormat::{,Large}{Binary,UTF8}Array.new(values) to build the underlying buffers directly from a Ruby values list.
Changes:
- Extend
VariableSizeBinaryArrayinitialization to accept a singlevaluesargument and build validity/offsets/values buffers internally. - Add new test coverage for initialization and equality behavior (including sliced arrays) across Binary/LargeBinary/UTF8/LargeUTF8 array classes.
