#1 Duplication pattern

[Johan Garcia]

Functionality for a duplication pattern could be implemented. One possible way could be to let the data value in the pattern signify the number of duplicate packets that should be generated. Another possibility could be to let the data value signify after how many packets the duplicate packet should arrrive. This later alternative however makes it harder to generate many duplicates of the same packet. A third possibility could be to split the data short into four 4-bit nibbles that each contain the distance to the preceding identical packet. This provides the ability to have up to four duplicates spaced with up to 15 packets between.
