hires and resolution rounding

[chrisgorgo]

I'm processing ds000009 and I noticed that hires is enabled. I was curious because it's an old dataset. However the resolution of the input data is:

pixdim1        0.999998
pixdim2        0.976562
pixdim3        0.976562

The hires was triggered by essentially not rounding the resolution: https://github.com/poldracklab/fmriprep/blob/bbc3727e6ba57dc485a2289831f557833ed3ddd8/fmriprep/workflows/anatomical.py#L89

I would recommend rounding it to 1 decimal place before doing the comparison
