Incorrect parsing of options with escaped quotes

trying to parse the string:

const curl = `curl -X POST "https://api.example.com/data" -H "Content-Type: application/json" -d "{\\"key\\": \\"This string has an escaped backslash: \\\\ and a newline: \\\\n\\"}"`;

Which is equivalent to the valid curl command

curl -X POST "https://api.example.com/data" -H "Content-Type: application/json" -d "{\"key\": \"This string has an escaped backslash: \\ and a newline: \\n\"}"

But when I parse it, my args array looks like the following:

_: [
        'curl',
        'https://api.example.com/data',
        'string',
        'has',
        'an',
        'escaped',
        'backslash:',
        '\\\\',
        'and',
        'a',
        'newline:',
        '\\\\n\\"}"'
      ],

Am I missing something or is this a bug?

Start by reproducing the exact JavaScript template string and parsing it with yargs-parser, then compare the resulting arguments with the expected curl arguments shown in the issue. Done means escaped quotes, backslashes, and the newline remain within the JSON argument instead of being split into separate arguments.
