Needed to upgrade MSRV to 1.6.5

error: package `time-core v0.1.1` cannot be built because it requires rustc 1.65.0 or newer, while the currently active rustc version is 1.64.0

Thanks. Don't you love it that those crypto crates change their API every release? This one isn't so bad, comparatively 😆

Would you please update the changelog to mention the MSRV bump?
