Option to use shortened album name

[RogueOneEcho]

The logic to suggest shortened album names already exists but there is no option to actually use this value:

caesura/src/naming/shortener.rs

Lines 39 to 62 in e803c44

	pub fn suggest_album_name(source: &Source) {
	if let Some(shortened) = Shortener::shorten_album(&source.metadata) {
	let before = SourceName::get(&source.metadata);
	let after = SourceName::get(&shortened);
	let difference = compare_char_count(&before, &after);
	if difference < 0 {
	info!(
	"{} directory could save {} characters: {}",
	"Renaming".bold(),
	difference * -1,
	after.gray()
	);
	}
	}
	}
	}
	fn remove_parenthetical_suffix(input: &str) -> Option<String> {
	let captures = Regex::new(r"^(.+)\(.+\)$")
	.expect("regex should compile")
	.captures(input.trim())?;
	let shortened = captures.get(1).expect("should have captures").as_str();
	Some(shortened.trim().to_owned())
	}

• Implement as --shorten-directory-name
• For consistency verify spectrogram transcode and upload commands would need to accept this.
• Apply to spectrogram output dir
• Apply to transcode output dir
• Apply to upload .torrent files
• Batch command should verify that the option is NOT enabled otherwise it could cause issues with matches.

Batch command will either skip the non-shortened version because it's too long. Or will skip because all formats are already uploaded.

That information could be save on the cache file for later commands. E.g. You run verify, spectrogram and transcode with --shorten-directory-name, but later when run upload forgot to use --shorten-directory-name.

• If album title includes (remix) or similar then this may get cut by --shorten-directory-name which should be avoided

For this reason I don't think there's value in shortening the album name and will close this as wontfix
