uri decode function

[osresearch]

Describe the bug
The @uri string formatter percent-escapes it's input, but there is no filter to reverse the process.

To Reproduce

$ echo '"="' | jq -r '@uri'
%3D

It seems that perhaps @text would convert it back, but it passes the string unmodified:

$ echo '%3D' | jq -R -r '@text'
%3D

Expected behavior
That there would be a @urid or similar to match @base64 / @base64d.

Environment (please complete the following information):

• Ubuntu LInux 20.04
• jq version 1.6

Same issue. This function is necessary for processing URLs in locales other than English.

Rosetta Code has a demonstration of an URL decoder in jq. It works for my use cases. Is it possible to integrate this code into jq?
