Use maps as opts (and other small cosmetic changes)

[NelsonVides]

Far too often I already have the opts for a pool created as a map and then I have to do maps:to_list/1. I think maps are just way too ubiquitous these days, it's a pity not to support them 😄

There are other cosmetic changes, like improving typespecs, upgrading plugin versions, using fully-qualified MFAs (the efficiency guide says they're somewhat faster function calls), and, increasing test coverage 🙂

Excellent contribution, as usual, @NelsonVides !!!

I'll give @paulo-ferraz-oliveira a day or two to review it and merge it. If he has not requested changes by Monday, I'll merge it and generate a new release with these changes.

And I don't have time to debug this on my machine.

Hmm... maybe something about versions? Updating the hex package or so? 🤔

[NelsonVides]

You can try adding me to hex and I'll see if I can publish docs
