Saved NFC parse error #671

Describe the bug.

Hi! I'm writing about an interesting issue I've found. This only happens to SOME NFC save files, not all. i.e. Mifare Classics don't seem to have an issue, but ISO15693-3 and NTAG/Ultralight (NTAG203) do.

Reproduction

Step 1: Scan some NFC tags with the latest official firmware (non unleashed). i.e. v0.96.1 Step 2: Install Unleashed firmware Step 3: Try to open up the files saved previously with the official firmware.

Conclusions: For some tag types, Unleashed doesn't support the latest version of file format. Here are some examples:

Tag file with official firmware:

As you can see, the file structure is a little bit different. I suppose this is why the NFC app cannot open some of the file types.

Suggestion: Update the app to support also the latest format.

Hello, v065 will not support new version of NFC files, install 066, all works correctly at v066
