Subject: [PATCH] fix: Support Restsharp 107+ (#179)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

After version 107, restsharp completely changed their API. This PR fixes the code generator to support the new API.
- also add the escaping function from https://github.com/Kong/httpsnippet/pull/289
- I think there are probably still escaping bugs here, but it seems to be working Well Enough™
