chore: benchmark the logger

[simonireilly]

Relates to aws-powertools#315

Loggers should be performant, baseline benchmarks should prevent performance regressions.

Description of your changes

This change adds benchmarked comparisons of the logger utility to existing eco-system loggers.

How to verify this change

npm i
npm run bench:deep --prefix packages/logger

Results:

benchLogger*10000: 12588ms
benchConsole*10000: 7.372s
benchPino*10000: 497.632ms

Simplified analysis, 12588 / 497 = 25; therefore to use this logger it would cost 25 times more on a lambda bill for the equivalent number of lines of logs.
