Attempt to fix it not being gcsafe

[lost-rob0t]

This is my First PR, please Correct anything that is wrong here.

I noticed when i was trying to use it with Prologue web framework that nim was complaining that it was not gc safe?
I found adding that flag had nim stop complaining about it.

Hey,
Does library still work today?

I thought it's broken since it uses some deleted functions in package macroplus

It definitely needs cleanup

Yup it works, Didn't even know about the changes.
Im not sure about the queryserver, I havent tried that.
But the normal CRUD Does work.

Thanks for pull request, I will make a new release when I tested it

[hamidb80]

what I really wanna do is to make APIs type-checked like what I did in my Bale bot API

I marked all of the responses as distinct JsonNode

I've tested it on CouchDB v3.3.2 (because couldn't find 3.1.1 binary for Windows).
_update and node_config API's does not work, anything else has no problem.

happy coding!
