Autoconversion of das2 streams to CDF files

Can now write das2 input to das3 datamodel in a streaming fashion,
The client API is 99.9% unchanged.  Calling DasIO_model(..., 3)
before running the pipeline with DasIO_readAll() is sufficent.

This allows the das3_cdf program to handle das2 streams natively.
