Cookie headers prefixed with $ are parsed incorrectly

Chrome will let you export a network call as curl by right clicking it -> copy -> copy as curl.

Chrome also likes to export long cookies like such:

curl 'https://someurl.com' \
  -H 'Connection: keep-alive' \
  -H 'Cache-Control: max-age=0' \
  -H 'sec-ch-ua: "Google Chrome"; v="83"' \
  -H 'sec-ch-ua-mobile: ?0' \
  -H 'DNT: 1' \
  -H 'Upgrade-Insecure-Requests: 1' \
  -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_15_3) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4093.3 Safari/537.36' \
  -H 'Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9' \
  -H 'Sec-Fetch-Site: none' \
  -H 'Sec-Fetch-Mode: navigate' \
  -H 'Sec-Fetch-User: ?1' \
  -H 'Sec-Fetch-Dest: document' \
  -H 'Accept-Language: en-US,en;q=0.9,it;q=0.8,la;q=0.7' \
  -H $'Cookie: somereallyreallylongcookie=true;' \
  --compressed

This gets parsed as

cookies = {
    '$Cookie: somereallyreallylongcookie': 'true',
}

in python, while in reality the $ should effectively be omitted, and the cookie itself should be parsed correctly.

Nice, great investigation!

Should be pretty straight forward to have it unescape strings prefixed with $'
