Support compressed requests
Some Graph API requests can be quite large (e.g. sending mail with attachments). It would be great if the Graph API supported POST HTTP requests that are compressed (i.e. "Content-Encoding: gzip”).
The Gmail API currently supports this.
This would also help when creating batch requests in order to time-efficiently upload a file + update its FileSystemInfo with just 1 API call (more info here: https://github.com/microsoftgraph/msgraph-sdk-dotnet/pull/412#issuecomment-502311274)
