Apply ANCOM to identify features that differ in abundance.
##########################################################

Apply Analysis of Composition of Microbiomes (ANCOM) to identify features
that are differentially abundant across groups.

Parameters
----------
table : FeatureTable[Composition]
    The feature table to be used for ANCOM computation.
metadata : MetadataColumn[Categorical]
    The categorical sample metadata column to test for differential
    abundance across.
transform_function : Str % Choices('sqrt', 'log', 'clr'), optional
    The method applied to transform feature values before generating
    volcano plots.
difference_function : Str % Choices('mean_difference', 'f_statistic'), optional
    The method applied to visualize fold difference in feature abundances
    across groups for volcano plots.

Returns
-------
visualization : Visualization
