Support for reading ANCOM-BC results (#68)

[SergioAlias]

Description:

This PR addresses the issue described in #68 where the current read_qza function does not support reading ANCOM-BC results (qiime composition ancombc). This update adds the necessary functionality to enable read_qza to correctly interpret and handle the multiple CSV files present in the QZA file.

Changes Made:

• read_qza.R:
  • Included "DataLoafPackageDirFmt" as a valid format.
  • Parsed CSV files included in ANCOM-BC result QZA file, so artifact$data is a list of data.frame objects
  • Renamed Intercept column in resulting data.frame objects since original column name, "(Intercept)", was being read in R as "X.Intercept." Columns are now renamed as simply "Intercept".
