描述

Currently, the sparsity score is calculated using a discrete count of values as a threshold. It might make more sense to refactor the SparsityDataCheck to use a relative threshold instead of a fixed count threshold.

SparsityDataCheck.sparsity_score(col, relative_count_threshold=0.10):
    <implementation>

Here the new relative_count_threshold should be a percentage of the total length of the column.
