Move CLI and progress indicators on its own feature

[ghimiresdp]

Description

• Now CLI and Progress Indicators are separated from the main download engine so that it can be attached whenever needed.
• Now the workspace is used so that we could add more packages inside crates and examples

Upon adding furl-cli library, users now have the choice to use the default features or select only needed ones.

Example, if you are creating a daemon and visual feedback is not needed, you can just skip visual feedback and use only core feature.

# Cargo.toml

[dependencies]
furl-cli = { path = "../../crates/furl_cli", default-features = false }
tokio = { workspace = true, features = ["rt-multi-thread", "macros"] }
