Increase MSRV to 1.41.0, as this was when profile-overrides landed

profile-overrides landed in 1.41 rust-lang/cargo#7591

I appreciate that the intention may be to maintain support for earlier rust versions if the profile-overrides keys are deleted from the README. But if the crate throws an error when compiled with its MSRV compiler, that in my opinion defeats the purpose of the MSRV.
