Consider changing log severity of double dispose so not critical

[quails4Eva]

I think to make the library closer to a drop in replacement to MemoryStream it would be good if double dispose wasn't logged as a critical, maybe information instead.

I understand the rationale for logging it and agree that it's useful, but given that double dispose is explicitly called out as being fine in the Stream docs, Asp.Net Core double disposes returned streams, and there's no negative impact in practice, I think critical seems like an overly severe categorisation.

I can manually filter/modify the logs for my app, but seems like something to consider changing in the library?
