Remove unnecessary dependencies

[nikhilr612]

The crate pretty_env_logger was added ad-hoc for momentary logging needs. A custom, non-fancy logger can be used since in most cases detailed logging within the crate is not required as much as clear, structured reporting to the user. Colors and formatting can be achieved by leveraging colored, or termcolor crates.
Moreover, certain tertiary dependencies like atty have introduced security alerts.
The dependencies need to be culled after careful consideration.

clap and env_logger are bringing in the most dependencies down the line.
regex is also an unnecessary secondary dependency

On the matter of coloured text output, anstream, and yansi seem like good candidates.
