Use order-n model for AC over Huffman implementation (#14)

I also tried searching along the alignment axis but it always found
align=0 to be best and it makes sense.
Although to be fair, I thought the same for order-n in high orders for
enwik7 but it turns out after 32 it starts degrading and a little
alignment helps.
I've also added some "log" files from runs on my MacBook M1 with 16GB
RAM - it must've gone to disk for ctx=34 order-n on enwik7.
