Support raw output mode

[ryochack]

The output of peep contains escape sequences.
This is a problem when using pipe or redirect.

$ cargo run -- -n 4 Cargo.toml > out.txt
$ vim out.txt
�[1G�[2K
lines�[2K
lines�[2K
lines�[2K
lines�[2K�[4F [package]�[m
 name = "peep"�[m
 edition = "2018"�[m
 version = "0.1.4"�[m

So, I will add raw-output-mode to peep to fix it.

will this enable colors in terminal as well?

[ryochack]

Thanks for your question.
No, this mode is only for outputting plain text without ANSI escape codes.

Unfortunately, I haven't had time to work on this issue lately, but...

Thanks for your hard work, I really love this utility. I'm learning Rust but I want to try to contribute

Thank you very much! I'm really glad to hear that.
