Performance

• Reduce startup time in loop-through mode (e.g. when redirecting output) by 90%. See #1747 (@Enselic)
• Load themes lazily to make bat start 25% faster when disregarding syntax load time. See #1969 (@Enselic)
• Python syntax highlighting no longer suffers from abysmal performance in specific scenarios. See #1688 (@keith-hall)
• Fix for poor performance when ANSI escape sequences are piped to bat, see #1596 (@eth-p)
• Fix for incorrect handling of ANSI escape sequences when using --wrap=never, see #1596 (@eth-p)
• Load custom assets as fast as integrated assets, see #1753 (@Enselic)

• Support for --ignored-suffix argument. See #1892 (@bojan88)
• $BAT_CONFIG_DIR is now a recognized environment variable. It has precedence over $XDG_CONFIG_HOME, see #1727 (@billrisher)

bat as a library

• Deprecate HighlightingAssets::syntaxes() and HighlightingAssets::syntax_for_file_name(). Use HighlightingAssets::get_syntaxes() and HighlightingAssets::get_syntax_for_path() instead. They return a Result which is needed for upcoming lazy-loading work to improve startup performance. They also return which SyntaxSet the returned SyntaxReference belongs to. See #1747, #1755, #1776, #1862 (@Enselic)
• Remove HighlightingAssets::from_files and HighlightingAssets::save_to_cache. Instead of calling the former and then the latter you now make a single call to bat::assets::build. See #1802, #1971 (@Enselic)
• Replace the error::Error(error::ErrorKind, _) struct and enum with an error::Error enum. Error(ErrorKind::UnknownSyntax, _) becomes Error::UnknownSyntax, etc. Also remove the error::ResultExt trait. These changes stem from replacing error-chain with thiserror. See #1820 (@Enselic)
• Add new MappingTarget enum variant MapExtensionToUnknown. Refer to its documentation for more information. Also mark MappingTarget as #[non_exhaustive] since more enum variants might be added in the future. See #1703 (@cbolgiano), #2012 (@Enselic)
