Longer normalized values

[jcassee]

Sometimes 20 characters is not enough for a value. A datetime with timezone, for example, is rendered as "2018-01-01 12:00:00+ ...". In other cases the value could be best rendered as a multiline string.

It would be nice to be able to influence the reporter in this way.

Yeah, I guess that can be increased and even apply a dynamic cut size depending on the value length. E.g: if len(x) < 50 display all else cut to 40 characters.

This size has been raised to 50 characters in #64 .
It seems to be enough to have complete datetimes and enough objects string representation to be relevant.

Maybe this issue can be closed for now ?
