Add parameter to `sliding_window` to end up with windows of (approximately) same number of cells

Could add a heuristic that tries to optimise the number of cells per window (and unassigned cells) so that on average, most windows have a number of cells assigned that is as close as possible to what the user specified.

Hi Tim, I agree this would be a really useful feature. More specifically, we could add the following parameters:

• max_nr_cells: int = None.
  • If not None, it calculates the window_size such that the number of cells in a sliding window is <= max_nr_cells (e.i. 1k).

Considering that given multiple library_key's the FOVs have different sizes or densities we could introduce a separate parameter that differentiates between whether the window sizes should be equal across all library_key's or not. For example:

• window_size_per_library_key: 'equal', 'unique'
  • 'equal': calculate one window size for all library_keys
  • 'unique': calculate a unique window size for all library keys

Hi @timtreis and @FrancescaDr , I'll work on this.
