Double64 should take 8 bytes, instead of 4.

I found this bug when I tried to read tags from a geotiff.

The original data was
7B 14 AE 47 E1 7A 84 3F ----- 0.01 index 0 - 7
7B 14 AE 47 E1 7A 84 3F ----- 0.01 index 8 - 15
00 00 00 00 00 00 00 00 ----- 0 index 16 - 23

but metadata-extractor read it like this:
7B 14 AE 47 E1 7A 84 3F ------- index 0 - 7
E1 7A 84 3F 7B 14 AE 47 ------- index 4 - 11 [should be 8 - 15]
7B 14 AE 47 E1 7A 84 3F ------- index 8 - 15 [should be 16 - 23]
