fixes #1140 DROID is getting stuck in an infinite loop trying to match the right fragments for [this signature](https://github.com/nationalarchives/pronom-signatures/blob/develop/signatures/fmt/134.json#L132) The steps are something like: 1. It finds matches for 7 of the 8 right fragments. 2. It adds these to a matched list 3. It doesn't find a match for the 8th fragment 4. It then searches each of the fragments in the matched list to either side of the previous matches. 5. Fragments 1-7 match and so stay in the matched list 6. The last matched fragment position is set to 7 7. The loop checking each fragment increments the fragment position to 8 8. It doesn't find a match for the 8th fragment 9. Repeat steps 3 - 9 The problem I think is step 6. It shouldn't be changing the loop counter. The issue is that I'm not 100% sure if by doing this, we'll be skipping some fragment checks which will cause a different format to not be matched at some point in the future. I don't think so though because the main loop still iterates through every fragment.

Do not increment loop counter.
