Benchmark this lib in general and against https://github.com/feliwir/libbig

BigEntry needs a _data: Vec<u8> field and a get_data(...) -> &[u8] function.

BigArchive can then grow read_entry(&str) -> &[u8] which can be written to disk.

• tests_file
• tests_bytes

Ideal usage:

$ sagebig list test.big art/

art/image.txt

This would list all of the entries whose names begin with art/.

This should probably accept art/ or art with the same results.

The readme has a list example but I accidentally left off the list subcommand from the text.

The current readme contains:

$ sagebig test.big

While it should say this:

$ sagebig list test.big
