575: Do no panic when passed empty string as argument. closes #466 r=Emilgardis a=sudipghimire533 When parsing argument `parse()` function in `src/cli.rs` splits the argument string without checking length which results in panic when splitting empty string. This PR pix that issue by introducing `continue` on empty string. Co-authored-by: Sudip Ghimire <[email protected]>
