staticcheck being included in go.mod pulls in a lot of unnecessary dependencies

[printfn]

Thank you for creating this library! Unfortunately there is an issue with how this repo includes staticcheck in the go.mod and tools.go files. Despite staticcheck only being used for linting, as a dev-only dependency, it is being pulled in as a standard dependency. This causes any other go package that uses go-cache to also pull in staticcheck and all of its dependencies, significantly increasing download and build times.

Since your Makefile simply invoked staticcheck as staticcheck ./..., this doesn't actually need staticcheck to be a dependency listed in go.mod, you can instead install it using go install honnef.co/go/tools/cmd/staticcheck@latest. This should let you remove it from the go.mod and tools.go files.
