rust: use `logging_timer` instead of `micro_timer`
I am the author of `micro_timer`.
I built it at the time because I couldn't find a crate that was simple to use
and flexible to do function timing with. Turns out I just couldn't find it
because crates.io's search isn't all that great, or maybe I didn't look hard
enough.
`logging_timer` is better in every way:
- supports changing the logging level
- supports start and end logging
- supports intermediary messages
- supports inline macros
- supports formatting the output
- better IDE/tree-sitter integration thanks to a more robust proc macro
I also changed all uses to one-liners, so it's easier to copy-paste.
