This is a new minor release version due to an added enum variant in StatusAttribute and the upgrade to nom 4 (which affects error types for parsing). Otherwise, the API is unchanged from before.

• Add support for HIGHESTMODSEQ status attributes to improve compatibility with Dovecot server (#28, thanks to @dario23)
• Made the parser slightly more lenient to improve compatibility with the DavMail server (#25, thanks to @vandenoever)
• Upgrade to nom 4.0 (#22, thanks to @theduke for taking care of this)
• Improved handling of INBOX folder names
