Last timepoint is (N-1)/N

Description

The following ZARR has 121 frames, numbered from 0 to 120. The denominator for the "Time" slider is 121, which sort of makes sense because there are 121 frames. But this doesn't look good when I go to the final frame and see "120/121", suggesting that there is another frame after the end

@lynwilhelm Can you remember if we discussed this before and had any conclusions on what is best? We can also reference things like FIJI or Zen etc.

[toloudis]

Zen and FIJI are both 1-based.

@pgarrison do you have a sense whether our web viewer should use 1-based or 0-based indexing when presenting these numbers to users?

[lynwilhelm]

The 1-based seems more intuitive to me but I only have a vague recollection of this discussion what I designed the sliders. @frasercl Do you recall and/or have a good argument for keeping it as-is?

I have a note to check in with scientists on this... will update here once I do that on Monday.
