Issue #2209: HEIF: Invalid input: No 'ftyp' box.

Adding a magic number for HEIC/HEIF, which would allow to discard
obvious non-HEIC images even with the wrong extension.

Note: it looks like this magic number would also match more generically
other ISO base media file format (ISOBMFF) formats, like .mov or .mp4
files. I am enquiring for better magic but for now, this is better than
nothing.
