Build fails without `cli` feature

[timvisee]

When building skim without the cli feature, building fails:

$ cargo check --no-default-features
    Checking skim v0.10.2 (/home/timvisee/git/skim)

Oops. This is obviously intended behavior as these failures come from src/bin/main.rs.

Building just the library works fine: cargo check --lib --no-default-features
