Incorrect minimal semver version for `getset` dependency

[regexident]

The getset dependency uses 0.1:

[dependencies]
getset = "0.1"

https://github.com/tjtelan/git-url-parse-rs/blob/main/Cargo.toml#L26

But the CloneGetters type is only available since 0.1.6.

This is causing semver issue for downstream crates.

The fix for this is straight-forward:

[dependencies]
getset = "0.1.6"

To reproduce install cargo-minimal-versions and then run this:

cargo minimal-versions check --workspace --tests --ignore-private -v

error[E0432]: unresolved import `getset::CloneGetters`
