v0.3.0

What's Changed

The bits that matter:

• More tests by @kgaughan in #20, #21
• passkit: a small library implementing the passlib functionality I need by @kgaughan in #23
• A TOTP (RFC 6238) implementation by @kgaughan in #25

Additionally, an issue with a workflow was flagged, and Sourcery started misidentifying test data as secrets:

• Potential fix for code scanning alert no. 1: Workflow does not contain permissions by @kgaughan in #22
• Avoid scanning test fixture data: can cause false positives by @kgaughan in #24
