Automatically fetches email titles for FSR MaPhy mailing list (by default for the last week) and formats in TeX code

To run, it needs log in credentials, provided via the environment:

-IMAP_PASSWORD
-IMAP_EMAIL
-IMAP_SERVER (defaults to 'imap.uni-potsdam.de')
-IMAP_FOLDER (defaults to 'Uni Mail/FSR', change this to the folder that contains only your [FSR MaPhy] mails, for example with Thunderbird message filters)
-IMAP_CUTOFF (iso string of cutoff date (inclusive), defaults to one week)

call via

 IMAP_PASSWORD=mypass python3 main.py 

or pipe directly to clipboard (using wl-copy on wayland):

 IMAP_PASSWORD=mypass python3 main.py | wl-copy

note the leading space, to not save password to bash/zsh history.
