Feature/siprec server (#143)

* fixes from testing

* modify Task#exec to take resources as an object rather than argument list

* pass 2 endpoints to Transcribe when invoked in a SipRec call session

* logging

* change siprec invite to sendrecv just so freeswitch does not try to reinvite (TODO: block outgoing media at rtpengine)

* Config: when enabling recording, block until siprec dialog is established

* missed play verb in commit 031c79d

* linting

* bugfix: get final transcript in siprec call
