L1t updates for 730

Substantial updates to the L1T emulation including:  serialization of new CaloParams ConfFormat object, packers/unpackers for Stage1Layer2 HW, algorithm updates.  CAVEATS:  a future PR should revert some config by local file, once new payloads are in a new GT.  Also, FED numbers (not presently assigned) for our hardware will need to added (in a bug fix) before production MC once they are assigned to us.
