Unexpected breaking behavior regarding backslashes

[Heimrych]

Description

gojq removes backslashes from double quoted string keys.

Version

gojq 0.11.2 (rev: HEAD/go1.15.2)

How to reproduce:

1 - Setup a file with a JSON containing keys that include doublequotes and require backslashes. Example:

{
  "aliasColors": {
    "{statuscode=\"200\"} 200": "green",
    "{statuscode=\"404\"} 404": "semi-dark-purple",
    "{statuscode=\"500\"} 500": "dark-red"
  }
}

2 - Run gojq in file.

gojq '.' issue.json

Expected behavior: It parses the file along with the backslashes, just like jq.

{
  "aliasColors": {
    "{statuscode=\"200\"} 200": "green",
    "{statuscode=\"404\"} 404": "semi-dark-purple",
    "{statuscode=\"500\"} 500": "dark-red"
  }
}

Actual behavior: It removes the backslashes, turning the JSON invalid.

{
  "aliasColors": {
    "{statuscode="200"} 200": "green",
    "{statuscode="404"} 404": "semi-dark-purple",
    "{statuscode="500"} 500": "dark-red"
  }
}

Thanks for reporting. I submitted a pull request to go-prettyjson library. But I noticed some inefficiency and low coverage of the lib, I'm thinking of switching to different lib.
