…rocessed for unchanged lines (Fixes java-diff-utils#219) (java-diff-utils#224)

- Introduces a new protected method `processEqualities(String)` in DiffRowGenerator
- Builder exposes `.processEqualities(Function<String,String>)`
- Equal (unchanged) lines now invoke processEqualities()
- Inline diffs remain unchanged (as expected in Option 3)
- Added new test suite DiffRowGeneratorEqualitiesTest
- Updated documentation and Javadoc for new extension point
- Fixes java-diff-utils#219 (HTML escaping issue when inline diff by word)

finalizeChunk() previously always created ChangeDelta regardless of
whether the hunk contained only insertions, only deletions, or only
context lines. This made it impossible for consumers to determine the
actual type of change from the delta alone.

Now uses InsertDelta when a hunk contains only additions (no context),
DeleteDelta when only deletions (no context), EqualDelta when only
context, and ChangeDelta otherwise. Hunks with context lines still use
ChangeDelta to preserve backward-compatible applyTo behavior.

Fixes java-diff-utils#201
