Norwin bbb287e29e markdown: dont emit ansi sequences when not emitting to tty (#491)
Allows generating a plain text version of an issue (i.e. without colors and other terminal formatting) when storing stdout in a file.
```
tea issue --comments 1 > issue1.txt
```

`IsInteractive()` had to be moved to avoid a recursive import chain.

---

In the future, it would be nice to also respect the `--output` flag. This flag is currently designed for tabular output, but we could add more supported values like `markdown` `ansi`, `plain` to it
