Feature request: Allow render of all time slot labels

[danyalejandro]

First, thank you for this wonderful library.

We are trying to build a calendar with time slots as in this example:

Note how there's a time slot with a label every 15 minutes (6:30 am, 6:45 am, 7:00 am, and so on).

I tried reproducing this with slotDuration: '00:15:00' but the library will skip printing the time label at odd rows, which in practice, will only print the label every 30 minutes. using slotDuration: '00:07:30' won't work as it will generate additional rows I don't want.

I believe this odd-even print logic is caused by the condition in packages/time-grid/src/Section.svelte:15:

<time class="{$theme.time}" datetime="{time[0]}" use:setContent={time[2] ? time[1] : ''}></time>

If the time slot label was printed for every row, it would satisfy my requirement (after some CSS fiddling). Could you please print the time slot label for every row, and hide it using CSS (i.e. using :nth-child(odd) and :nth-child(even) classes)? Or perhaps make it a configuration flag?

I'm open to contributing a PR if you're too busy to implement this.

Good idea. I will implement this later.
