ne 3.0.1 (new formula)

This adds a formula for the ne text editor. Ne is a lightweight
text editor with a focus on performance and little bandwidth use.
Apart from that it is designed to be approachable yet extensible
enough to keep an advanced user productive.
Development is located at https://github.com/vigna/ne.

Improve test and incorporate other feedback.

Set TERM hoping to get the CI tests to pass.

Use wrapper around ne

Closes Homebrew/legacy-homebrew#45531.
