read tiff image sequence

[nclack]

Option 1

For filenames like path/to/data/something_%05d_blah.tif, using printf style formatting.
Would be nice to infer first number and increment from there, but will probably just start from 0.

Option 2

Need to be able to drag and drop.
If it's a single image tiff, look for numbers in that name,and go from there.
