Make transitive dependency on unzip-stream and tar optional

Users of this package should only need to have a transitive dependency on tar/unzip-stream if they actually use binaries that are compressed in those formats.

Start by inspecting the package dependency declarations and the entry points that handle binaries compressed with tar or unzip-stream. Determine how installations behave when those dependencies are absent, then verify that users who do not use those formats can install and use the package without them while compressed binaries still work when the dependencies are available.
