Migration to `purescript-logging`

[paluh]

I think that using existing logging methods from the ecosystem could be beneficial as we could avoid reimplementation of specific loggers or adapters in this repo. I'm proposing moving to purescript-logging which has really similar structure to the current logging type and has already existing loggers which could be useful (for example my binding to the journald).

What do you think?

I haven't put much thought into logging yet in Payload - mostly it just dumps strings in various places, and provides a log level hook to get more debug information - but there could definitely be a better story there. I'll check this out.
