> When writing a regular expression with a named capture group, underscore can't be used.
> Typically, underscore is a valid character for capture groups. As avro also supports underscores, and GrokReader is used to write into avro schemas, this should be fixed.
> Example of non-working regex:
> (?<my_namedcapturegroup>.*)
