Add method to DynamoDB Stream Event AttribubuteValue to return the proper type for that AttribubuteValue

[gwlester]

Is your feature request related to a problem? Please describe.

When attempting to transverse a DynamoDB Stream Event, it would be nice to know the datatype of an AttributeValue so the correct call to get the value could be made. I.E. string vs list vs map.

Describe the solution you'd like

Add an AtributeValue method that would return the type of value for that attribute. It would be also nice to have enumerated labels for the types.

Describe alternatives you've considered

We always get all three and test the class.

@gwlester I have a PR for this #462.

Can you check if this is what you want.

[gwlester]

Since the PR got merged -- should this issue be closed now?

Just asking,

[michaelbrewer]

@gwlester kind of, us to you ;-). Once it is deployed, maybe you can help validate that it works for you.

Closing this now as it's already available in PyPi too :)

Thanks a lot @michaelbrewer for the implementation
