 Description   

I am not sure how non-standard this is but some FAST implementations include a block size in the message that OpenFAST does not expect causing the codec to fail.

Below is what I have done to fix it in my local copy of the code.

I'm not sure how to handle configuration properties for the CODEC so I can make it switchable - should it hang of the Context or elsewhere?

There is a readMessage(int offset) method in FastDecoder which can be used to skip a non-FAST header or block length.

Additionally there is a MessageBlockReader interface that can be implemented and assigned to a MessageInputStream.

The FastDecoder.readMessage(int offset) method was added in 1.0.3.
