Fix CR3 detection #310

Closed qbnu closed 5 months ago

qbnu commented 5 months ago

261 broke CR3 detection. CR3 uses the HEIF container, so it gets detected as a HEIF before checking the file extension.

I added a check for the "crx " major brand and moved the unspecified encoding fallback after the file extension check. I moved TIFF detection here as well, which currently won't really do anything since it just goes to GDI+ anyway. I also added the .HIF extension used by newer Canon cameras (https://github.com/lclevy/canon_cr3/blob/master/heif.md)
