RUSTSEC-2024-0384: Unmaintained transitive dependency

[turmanticant]

Describe the bug

Hey! I use cargo-deny and noticed I was getting an error for one of tantivys transitive dependencies.

measure_time depends on instant which has been marked as unmaintained. There is no security vuln associated or anything requiring immediate action as best as I could tell.

There is only one place in tantivy I could see that uses measure_time, src/indexer/merger.rs.

It is importing the debug_time macro and using it to instrument a few methods.

        debug_time!("write-fast-fields");

Given the small usage here, could this replaced with a log::debug! and remove the dependency to measure_time? If so, I'm happy to open a PR doing that. 😀
