Energy descramble

ETSI EN 300 744 - Clause 4.3.1.

Input 
Randomized MPEG-2 transport packets.
Output 
MPEG-2 transport packets (including sync - 0x47).

We assume the first byte is a NSYNC. First sync in a row of 8 packets is reversed - 0xB8. Block size is 188 bytes.

Parameters

Blocks 
number of blocks.

Example Flowgraph

Insert description of flowgraph here, then show a screenshot of the flowgraph and the output if there is an interesting GUI. Currently we have no standard method of uploading the actual flowgraph to the wiki or git repo, unfortunately. The plan is to have an example flowgraph showing how the block might be used, for every block, and the flowgraphs will live in the git repo.
