Implement "title" field of NIP-52

[vicariousdrama]

The title field is a required tag for date and time based calendar events (kind 31922, 31923). Currently, flockstr only supports the deprecated name field. Recommend looking for title, using it, and falling back to name if title is not present

Hi! Thanks for flagging this in #13. I’ve just opened PR #18 to address it (link). It adds support for the NIP-52 title field and gracefully falls back to the deprecated name field if title isn’t present, exactly as suggested. This should fully resolve the issue for date/time-based calendar events (kinds 31922/31923). Feel free to take a look when you get a chance! 😊
