Does this PR already have an issue describing the problem? No

What kind of change does this PR introduce? Feature

What is the current behavior? All the existing DataSources based on files extend FileDataSources. The difference between datasources considering files in a directory and the datasources considering files in an archive is not clear enough.

What is the new behavior (if this is a feature change)? Two types of DataSources based on files now exists:

• DirectoryDataSource (inherited by GzDirectoryDataSource, Bzip2DirectoryDataSource, ZstdDirectoryDataSource, XZDirectoryDataSource): considers files in a directory
• AbstractArchiveDataSource (only ZipArchiveDataSource for now but a TarArchiveDataSource could be added later): considers files in an archive.

Does this PR introduce a breaking change or deprecate an API?

• [X] Yes
• [ ] No

If yes, please check if the following requirements are fulfilled

• [X] The Breaking Change or Deprecated label has been added
• [X] The migration steps are described in the following section

What changes might users need to make in their application due to this PR? (migration steps) Two types of DataSources based on files now exists:

• DirectoryDataSource (inherited by GzDirectoryDataSource, Bzip2DirectoryDataSource, ZstdDirectoryDataSource, XZDirectoryDataSource): considers files in a directory
• AbstractArchiveDataSource (only ZipArchiveDataSource for now but a TarArchiveDataSource could be added later): considers files in an archive.

Therefore, multiple classes have changed, please update your code if you used them directly:	Old classes	New classes
Bzip2FileDataSource	Bzip2DirectoryDataSource
FileDataSource	DirectoryDataSource
GzFileDataSource	GzDirectoryDataSource
XZFileDataSource	XZDirectoryDataSource
ZipFileDataSource	ZipArchiveDataSource
ZstdFileDataSource	ZstdDirectoryDataSource

Note: Their constructors are not the same so you will have to adapt your code to the new ones, depending on which DataSource you use.
