Whoops, log spam: change server to INFO log level

0.2.1

• Initialize server logging at INFO level to prevent log spam (commit a805187)

Convert server to mio and do some housekeeping

0.2.0

Changes in 0.2.0 are internal and non-breaking to client code, but extensive enough to warrant a minor version bump out of caution.

• Replace the server's hand-rolled recv_from loop with a legit mio event loop (commit ae47aa8).
• Learn how to use Rust string byte literals correctly (finally!) to de-fuglify the Tag::wire_value map (commit 270d6a6)
• Switch to simple_logger instead of fern (commit ca97eff)
• Remove patch version from dependencies in Cargo.toml (commit 05479fa for rationale)
• Clippy changes/cleanups (commit 1096512)

Update dependencies and publish to crates.io

• Refresh Cargo.toml with current versions of dependencies
• Update crate-level docs to be friendlier
