Support for more archive types?

[GreatEmerald]

While ESPA provides downloads in .tar.gz format, it's using DEFLATE for compression which is not ideal for conserving storage space. Recompressing the files into .tar.bz2 or .7z (with LZMA or PPMd algorithms) saves a lot more space (around 100 MiB for each archive of 5 Landsat 8 bands). But that creates extra problems in that bfastSpatial can't handle such files any more.

The package archive allows handling various archive types. It also allows extracting single files from archives, which would further help decrease the required tmp space.
