Do not force-wrap text when output to file (or piping)

**Describe the bug**
When text is output to a file, it is always wrapped at position 79.
Lines shorter than 79 characters are padded with spaces until they reach this length.

**To Reproduce**
```
pytgpt generate --quiet --disable-conversation "Write a short story">output.md
```

**Expected behavior**
I expect  that the output should not be reformatted/padded in any way.
