feat: add phuslu/log

[Juneezee]

phuslu/log is another logger that claims to be faster [reference] than both uber-go/zap and rs/zerolog.

This pull request includes phuslu/log into the benchmark results. However, currently the logger is not compatible with the test validation because the timestamp field is always enabled, and the duration encoder is string (e.g. 1ms) rather than int (e.g. 1).

Test failure due to timestamp can't be disabled in phuslu/log Fixed by delete(got, "ts") in L437 of main_test.go

Test failure due to different time and duration encoding being used in phuslu/log

phuslu/log outputs the current time if the given TimeFormat is empty, which is causing some of the validations to fail as well.

This pull request is ready when phuslu/log#29 is resolved.

Will this lib be added to your overview?
phuslu/log#29 (comment)

Why are timestamp usually disabled?
