imap flags
I added a new fetch_flags method to the imap class, specifically for retrieving only the IMAP flags of messages. Additionally, I modified the original fetch method so that it now requests the flags from the server when fetching the message. I added a std::vectorstd::string element called flags that stores the flags received from the server in their original format (e.g., \Seen). This implementation also supports custom flags.
Hey, thanks for the contribution. That was also on my agenda to add it. Please be patient for merging this PR. I have IMAP tests for various functionalities but they are not public. Since I am doing refactoring regarding line policy, folding and related stuff, I cannot immediately take a look of your PR.
