Fix literal flag not being recognized from config file

[Akmadan23]

The literal option was not correctly recognized from config file due to Literal::from_cli returning Some(Literal(false)) instead of None, so Literal::from_config would never have been executed.

TODO

• Use cargo fmt
• Add necessary tests
• Update default config/theme in README (not applicable)
• Update man page at lsd/doc/lsd.md (not applicable)
