Describe the requested improvement
One of the arguments of the function sits_accuracy() is "validation", which are the samples to validate the classification.
According with the documentation "The validation data needs to contain the following columns: "latitude", "longitude", "start_date", "end_date", and "label". It can be either a path to a CSV file, a sits tibble or a data frame"; please allow this argument to be in "sf" format and contain the same columns
