If arg `radius` is not specified, the function returns the entropy of the cell types of interest for the whole image. If arg `radius` is specified, the function returns a data frame where each row is a reference cell and the columns stores the entropy of the cell types of interest in each circle of the reference cells.

)SpatialExperiment object in the form of the output of
format_image_to_spe.
String Vector. Cell types of interest. If arg `radius` is not NULL, the first cell type is considered as reference cell type. Circles of the specified radius will be drawn around the reference cells and the entropy of cell types will be calculated for each of the reference cells.
String specifying the column the cell types are from.
(OPTIONAL) Numeric. The maximum radius around a reference cell for another cell to be considered an interaction.
A dataframe or a number depending on the argument radius
