Wikimedia downloader (aka wmd)

Initial goals:

• Write a cronjob to run on a server that runs a tool to download the latest English Wikipedia database dump.
• Once a new dump is successfully downloaded older versions should be deleted (perhaps keep the latest 2 dumps).

To run

# For usage and help
cargo run -- --help

# To download the latest version of a small example job
cargo run -- download --mirror-url https://ftp.acc.umu.se/mirror/wikimedia.org/dumps \
                        --dump enwiki \
                        --job namespacesv2

Set the environment varible RUST_LOG to configure logging levels and filtering. This application uses the tracing-subscriber crate for logging, see their documentation for the available logging configuration directives. Note that many of these directives can be supplied separated by commas.
