It would be great to allow:

• Adjustment of histogram bin width / locations via the UI
• Using integer bin limits for integer images (e.g. uint8, uint16)

For example, if you show the coins image in Napari (File > Open Sample > napari builtins > Coins) and view the histogram, it has an odd 'spiky' appearance where every other bin is higher or lower:

I think this is because the limits of the bins aren't set to integer values (even though this image is uint8 and therefore only contains positive integers). E.g. I think the bins are np.linspace(1, 252, 100) according to here, so for example bin 20 onwards is: 51.7, 54.2, 56.7, 59.3, 61.8, which means the bins accept pixel values of (52, 53, 54), (55, 56), (57, 58, 59), (60, 61)... This alternating of 2 and 3 pixel values in each bin gives this spiky appearance which is a bit misleading to the actual values. Would it be possible to set integer bin edges, or allow this to be set as an option? Thanks!
