• Extension::from_path
• Extension::is_empty

  • Replaced Extension::new2/new3/new4 w/ Extension::new
  • Replaced Extension::try_from2/try_from3/try_from4 w/ Extension::from_path
  • Removed Extension::slice_ext2/slice_ext3/slice_ext4 (use std::path::Path::extension instead)
• Hash for Extension now uses Hasher::write_u64 for all values
• Removed PartialEq<AsRef<Path>> for Extension (use Extension::matches_path instead)
• Removed Extension::codegen (use const {} assignments instead)
• Removed Extension::slice_ext (use std::path::Path::extension instead)
