Option to keep output simple for piping purposes

[yamanawabi]

Hello,

Thank you for the wonderful tool. I appreciate the postman functionality distilled into an awesome cli app.

Is your feature request related to a problem? Please describe.
I am hoping to add a feature to Poodle that will prevent any colorization of the output, as well as remove the spinner when this command line option is called. The reason I would like to add this is because I like to view JSON output in the cli via jq. Adding this flag would allow me to pipe the output from Poodle into jq or even for simple output redirection (saving json files).

Describe the solution you'd like
I have made a fork of the repo and added the changes (-b, --bare-only). However as this is my first time working in Go, I figured I would ask for some pointers here before attempting to make an official pull request. I want to make sure that a PR is clean and up to the standards when completed.

Additional context
Hoping to gain some experience in contributing to public projects and with Go. Thanks again!
