Bump collection version number to 3.1.0

The only changes since the last release are those introduced by #18.

According to https://semver.org/spec/v2.0.0.html:

- "6. Patch version Z (x.y.Z | x > 0) MUST be incremented if only backward compatible bug fixes are introduced. A bug fix is defined as an internal change that fixes incorrect behavior."
- "7. Minor version Y (x.Y.z | x > 0) MUST be incremented if new, backward compatible functionality is introduced to the public API. [...] It MAY be incremented if substantial new functionality or improvements are introduced within the private code."
- "8. Major version X (X.y.z | X > 0) MUST be incremented if any backward incompatible changes are introduced to the public API."

PR #18 qualifies both as "substantial new functionality or improvements are introduced within the private code" and "backward compatible bug fixes", thus I am increasing the minor version number.
