Code:

 
 
2 byte -> number of words to repeat + 2 words
2 byte -> word to repeat
2 byte -> abs(number of wordd to next code)
so 000F = 15 words (1 word = 2 bytes)  + 2 more words = 17 words or 34 bytes
this means there should be 34 bytes of 0
if you look at the decompressed,  there is 2 rows, plus 2 additional bytes.  16 + 16 + 2  = 34
you need to find a way to come up with a tool to do this
var repeatCount = readword();
var valueToRepeat = readword();
var rawReadCount = readword();

for(i = 0; i <= repeatCount() + 1; i++)
{
     output.add(valueToRepeat);
}
for(i = rawReadCount; i < 0; i++)
{
     output.add(readword());
}
