Fix all clippy warnings (beta toolchain version 1.92.0-beta.3)

This ignores a false positive (at least it seems to me that way) of the
`redundant_iter_cloned` lint that is present since toolchain v1.92:
- https://rust-lang.github.io/rust-clippy/beta/index.html#redundant_iter_cloned
- rust-lang/rust-clippy#15725
- rust-lang/rust-clippy#16012
