Implement Drop for Blink adapter

[dmitry-salin]

Blink adapter docs contains:

/// [`Blink`] calls [`Drop::drop`] for emplaced values when reset or dropped.

But in fact it only does this when reset.

Thanks for noticing this!

[dmitry-salin]

Thanks for quick response. It seems I needed to apply fmt to the entire project. Also clippy with --all-features flag is failing on stable.

[zakarumych]

Yeah, they change set of lints and it's typical for check to fail after some time.
If it's not too much, please, add clippy fixes.

[dmitry-salin]

actions-rs is no longer maintained. One issue affecting this PR: clippy-check error. I suggest switching to actions-rust-lang and clippy-action.

Looks great!
