Simply run fails

Hi,

I am following the instructions on https://corpaul.github.io/flamegraphdiff/.
After cloning this repo and navigating into the flamegraphdiff directory, I attempted to execute the following command:

$ FlameGraph/difffolded.pl demos/rsync/rsync_v2.txt demos/rsync/rsync_v1.txt | FlameGraph/flamegraph.pl > demos/rsync/rsync_dfg1.svg
However, I encountered several errors / warnings:
..
Use of uninitialized value $count in addition (+) at FlameGraph/difffolded.pl line 97, line 6940.
Use of uninitialized value $stack in hash element at FlameGraph/difffolded.pl line 96, line 6941.

ERROR: No stack counts found
Could you please help me resolve this issue?

Thank you!

After using the zip file in download .zip and copying FlameGraph folder from your latest repo, everything runs!

It seems that the latest version of the repository doesn't sync with the usage instructions on https://corpaul.github.io/flamegraphdiff/.
