smartcd: make fd optional: add support for find command

Also `SmartCd` will show search results from directories that would otherwise be ignored by
- `.gitignore`
- `.git/info/exclude`
- the global gitignore configuration (by default `$HOME/.config/git/ignore`)
- `.ignore`
- `.fdignore`
- The global fd ignore file (usually `$HOME/.config/fd/ignore`)
