Drag and drop example doesn't work on Safari

[jakeleventhal]

When dragging in a PSD I get this error in the browser console:

[Error] panicked at 'already borrowed: BorrowMutError', /rustc/fd4b177aabb9749dfb562c48e47379cea81dc277/src/libcore/cell.rs:877:9

What happens if you use the psd crate to deserialize the bytes?

As in, what happens when you call this method on your PSD https://docs.rs/psd/0.3.5/psd/struct.Psd.html#method.from_bytes ?

This will help us rule out whether it's an issue with the demo or an issue with the parser.
