Release v0.1.0

[FelixMcFelix]

This PR will update dependency versions to crates.io versions in preparation for a full crates.io release, and integrates the first version of Songbird's changelog.

Currently, this is blocked on the release of serenity v0.10.0, serenity-voice-model v0.10.0, and twilight v0.3.0. The new serenity versions are needed as a bare minimum, and since these are poised to make the swap over to tokio v1.0 we also need to wait on the next twilight version.

After this is merged, the project will strictly adhere to semver: breaking changes will be merged to next, while patches and new features which do not break API compatibility will be merged to current.

Changelog is below:

0.1.0 — 2021-01-08 — Robin

We're very excited to publish and announce the first release of Songbird, an async Rust voice library for Discord!
It's been a long time coming, but all the hard work has paid off in bringing the first version of this library to completion.

Thanks to the following for their contributions:

• @acdenisSK
• @FelixMcFelix
• @Maspenguin
• @peppizza
• @saanuregh

Songbird is based heavily on serenity's voice module, which has served as its base design, informed many of the design changes, and paved a lot of the API/protocol research needed.
We'd also like to thank all users who have contributed to this module in the past for laying the groundwork for Songbird:
