Performance issue: stripComments blocks event loop for 12s

We did a CPU profiling for our node app and noticed that the query normalization blocks event loop for quite a while:

[stripComments](https://github.com/gajus/slonik-interceptor-query-normalisation/blob/master/src/utilities/stripComments.js) function was taking 12 seconds in one long SQL query we were using.

Wanted to report this for others possibly investigating the same, feel free to close. Unfortunately I don't have a reproducible query example.

Start with src/utilities/stripComments.js and the CPU profile described in the issue. Investigate the reported event-loop blocking using a long SQL query, but note that the issue provides no reproducible query or specific requested change. Completion criteria are not defined beyond addressing the reported 12-second delay.
