[DOP-8959] Add Excel file format support

[dolfinus]

Change Summary

• Added Excel file format, based on https://github.com/crealytics/spark-excel. Supports only Spark 3.2+. Can read both .xlsx and .xls files, but write only .xlsx.
• Not all Spark versions are present in Maven index for this package, e.g. Spark 3.2.4 support was added in package version 0.19, but Spark 3.2.3 was supported only in 0.18.6/0.18.7. Because of this, Excel.get_packages() method also has package_version attribute, which should be chosen according to Spark version used.
• Because of previous item, Spark 3.2.3 in CI build matrix was replaced with 3.2.4
