Check minimum version dependency

[kawasin73]

cargo usually downloads dependencies as higher versions as possible. The CI can't catch the dependency version mismatch with the minimum versions. (e.g. #65)

The CI should run tests with the minimum versions as well. minimum versions can be downloaded by this cargo command.

cargo +nightly update -Z minimal-versions
