KMS::Client.decrypt StringIO to String conversion errors since v2.0.15

[tim-george]

Since v2.0.15 all calls to KMS::Client.decrypt are failing with conversion errors.

My guess is that in light of the change to aws-sdk-core/lib/seahorse/client/param_converter.rb:203, aws-sdk-core/lib/aws-sdk-core/json/builder.rb:54 might need to be changed from "value" to "value.read".

Best illustrated with the following:
