Tags are a slice of strings in the documentation, but datadog-go documentation does not mention valid values for tags. datadog-go removes newlines from tags, but does not remove/escape other invalid characters like comma (,). Comma in tag value will be interpreted as multiple tags since tags are comma-separated in the UDP datagrams.

The page at https://docs.datadoghq.com/developers/guide/what-best-practices-are-recommended-for-naming-metrics-and-tags/ lists recommeded practice for naming tags, perhaps datadog-go should provide a function to sanitize the tag values according to those rules?
