Slack integration error when username is too long

[konifar]

Hi, I love tonkotsu 🐷
I found a problem (not bug) that slack integration failed.
If my config.toml was like this below, Aoba-chan posts nothing to slack.

[slack_start_post]
text = "新バージョンのアプリが更新されるまでGooglePlayStoreをチェックします！"
username = "青葉ちゃん（GooglePlayStore監視ツール）"
icon_emoji = ":aoba:"
...

And then, I found the cause. It is because the username is too long.
When I changed name to just 青葉ちゃん, It was succeeded.

Maybe this is slack matter. But I guess it is better to show log like Username should be within xx characters.. How do you think?

Thank you for issue report!

Good idea. I will try to check up on how long use characters.
