0.16.4

• iPhones show "Sent" when a transfer finishes. After a completed upload, the receiver kept the connection open, so the iPhone stayed on "Sending" until the receiver's 30-second idle limit closed it. The file had already been saved. The receiver now answers a completed upload with Connection: close and closes the connection straight away. Discover and Ask answers are unchanged (#51, #69, @shaecodes-wilde).
• Contacts Only works with OpenSSL 3.0. On Debian 12 and Ubuntu 22.04 and 24.04, the receiver couldn't read the Apple account from a sender's verified certificate, because OpenSSL 3.0 formats the certificate subject differently. Every sender was refused, including known contacts. The account is now read the same way on every OpenSSL version (#67, @MrSco).
• Driver unchanged. omdrop install-driver still builds omdrop-awdl 0.9.3.
