Release version 0.3.0

[psivesely]

After #74 is merged. #74 will fix #71, and is a breaking change (since it includes semver breaking updates of multiple dependencies), so it will have to be version 0.3.0 instead of version 0.2.3.

Hi there, I would love an updated release as I’m runnign into that ring build error with a tool I have using rustysecrets. Thanks for your work on this crate!

Could someone look into build/CI issues with #74? I won't have time to get to it this week myself, but can take care of releasing 0.3.0 once it's merged. Otherwise I will get to it myself next week.

I will if I have time. Just post a comment here if you're going to start working on it and I'll do likewise so that we don't reproduce work esp. since we're sharing that feature branch.
