R/calculate_minimum_distances_between_celltypes.R
    calculate_minimum_distances_between_celltypes.RdReturns the distance of the closest cell of a specific type from each reference cell.
calculate_minimum_distances_between_celltypes(
  spe_object,
  feature_colname,
  cell_types_of_interest = NULL
)SpatialExperiment object in the form of the output of
format_image_to_spe.
String of the feature column of cells to choose the cell types from (e.g. Cell.Type, Cell.Type2, etc).
String Vector of marker combinations to consider is FALSE.
A data.frame is returned
