Added support for SDS2000X HD models based on the work of gralco (Eric Kuzmenko) in this PR : github.com/sigrokproject/pull/176/

Created a new protocol version "E11" matching the latest Siglent SDS Scope programming guide.
Reduced the read-wait time from 7sec to 50ms for better performance (achived by looping on read sample logic to consume the data has it arrives).
Tested with SDS2504X HD model connected via Ethernet cable.
