configure method

void configure({ bool? showLineNumbers, bool? wrapLines, bool? zeroPadLineNumbers, DiffViewMode? viewMode, DiffStyles? styles, List<DiffCommentLineHighlight>? commentHighlights, })

Configures display options.

When rendering-relevant options change (viewMode, showLineNumbers, wrapLines, zeroPadLineNumbers, styles), the diff lines are re-rendered automatically.
