Very large images cause std::bad_array_new_length in Sift due to overflow of INT type

[Oblomov]

Trying to process 3 images with these characteristics

img1.tif TIFF64 39164x57303 39164x57303+0+0 16-bit Grayscale Gray 4.18103GiB 0.000u 0:00.000
img2.tif TIFF64 39378x57512 39378x57512+0+0 16-bit Grayscale Gray 4.21921GiB 0.000u 0:00.000
img3.tif TIFF64 39611x59355 39611x59355+0+0 16-bit Grayscale Gray 4.38017GiB 0.000u 0:00.000

causes Sift to throw an std::bad_array_new_length error. Compiling the current master with debug info shows that the issue is the use of the INT type (that maps to int) for file and/or memory sizes, which with these images results in an overflow :

Supporting these images probably requires the use of 64-bit integers for these memory-related data types.
