Advisories for Nuget/MessagePack package

When this library is used to deserialize messagepack data from an untrusted source, there is a risk of a denial of service attack by an attacker that sends data contrived to produce hash collisions, leading to large CPU consumption disproportionate to the size of the data being deserialized.

When this library is used to deserialize messagepack data from an untrusted source, there is a risk of a denial of service attack by either of two vectors: hash collisions - leading to large CPU consumption disproportionate to the size of the data being deserialized. stack overflow - leading to the deserializing process crashing.
