Migration

Note that the top-level type changed from Message to Report.
Message is now a single block of text within a Report.

• Replace Message::footer with either
  • adding a Message to a Group
  • starting a new Group
• Replace Level::<Variant> with Level::<VARIANT>, e.g. Level::Error -> Level::ERROR
• Instead of creating Snippets on a Message (the type returned by Level::title), add them to the Group that is created with the Title
• Snippet::origin has been renamed to Snippet::path
• Instead of creating an Annotation from a Level, create them from an AnnotationKind
  • AnnotationKind::Primary will automatically match the Level of the Group
  • All others existing annotations should likely be AnnotationKind::Context
• Level::title has been replaced with Level::primary_level (for first Group) and Level::secondary_level (subsequent Groups)
• Message::id has moved to Title::id
• Renamed Renderer::line_no to Renderer::line_num
• Add snippet.fold(false) if unspecified, removing snippet.fold(true) if specified

Features

• Added unicode decor support, see renderer::DecorStyle
• Created [Group] to indicate what all is included between the unicode begin and end decor
• Added Level::secondary_title to allow for custom ANSI escape code styling to be applied to those Titles
• Added AnnotationKind::Visible to force spans to be visible within a Snippet, despite code folding, without any visible marker
• Added Origin for referencing code without the source
• Added Group::with_level to allow Snippets without a Title
• Added Level::no_name to hide the level name
• Added Level::with_name to override what is rendered for that level
• Added Title::id_url to turn Title::id into a link
• Added Patch for displaying changes to code

Fixes

• Switched strings to Cow<str> to allow for easier management of owned data
• Snippet::path now accepts None
• Annotation::label now accepts None
• Various rendering fixes
