Require sysinfo crate version with the breaking API change

[teor2345]

Recently, vergen fixed a breaking change in the sysinfo API.

But the fix only updated the code, and not the sysinfo crate version requirement. So downstream builds that require an older sysinfo version may fail.

Can vergen require a sysinfo version that's greater than or equal to the first version with the new API?

vergen/Cargo.toml

Line 31 in 429f0c2

sysinfo = { version = "0", optional = true, default-features = false }
