Strip escape characters from an escaped string using two double quotes as escape

[josdejong]

In many programming languages, a backslash is used to escape quotes in a string, like:

"{\"stringified\": \"content\"}"

Some languages though use a pair of double quotes to escape, for example batch scripts and C# verbatim string literals, . For example:

"{""stringified"": ""content""}"

The jsonrepair library already can repair escaped contents using backslash. It would be nice if it can also repair pairs of double quotes.
