Add a CHANGELOG entry for -config
* New metrics `ssf.spans.tags_per_span` and `ssf.packet_size` track the distribution of tags per span and total packet sizes, respectively.
* Our super spiffy logo, designed by [mercedes](https://github.com/mercedes-stripe), is now included at the top of the README!
+## Deprecations
+* `veneur-emit` no longer supports the `-config` argument, as it's no longer possible to reliably detect which statsd host/port to connect to. The `-hostport` option now takes a URL of the same form `statsd_listen_addresses` takes to explicitly tell it what address it should send to.
