[Bug]: candy machine v2's verify_assets CLI miscounts images in current directory

[sfdz]

Which package is this bug report for?

candy-machine

Issue description

The verify_assets command has an off-by-one error when it counts the number of images in the current directory.

Steps to reproduce:

• Create a directory with nft metadata, in my case 100 items
• Verify that the number of files is correct

  % ls | wc -w
   200

• Run verify_assets from within that directory

  % npx ts-node ~/Documents/metaplex/js/packages/cli/src/candy-machine-v2-cli.ts verify_assets .
