.wiff2 container

.wiff2 is SCIEX's newer single-file format, combining the metadata held in a legacy .wiff file and the scan data held in its .wiff.scan companion. It is an encrypted container.

Decrypting .wiff2 is out of scope for this project. OpenSXRaw does not read .wiff2 files and there are no plans to add support. Use the legacy .wiff + .wiff.scan pair when the acquisition software can export it.
