Refactor

I rewrote the request part, modified the json_body , and appended the xml_body.

It's perfectly work with helix editor.

Hey, I'm loving all the changes but why did you remove embedded JSON parser and rolled out a custom one? Just being curious there.

Cheers

The reason is that like vim, helix tree-sitter has support injections.scm, by setting injections to support json, xml, reduce the size of the compiled file.

Woops, I've been somewhat busy and completely forgot to merge this one, my apologies!

Thank you so much again for the changes!

[erasin]

Thanks merged.
In helix pr, use hurl replace rest-client.
Because helix not support plugins now, and the hurl support cli and chaining request.
