release 1.1

[Dan Callaghan]

I've just released Sup 1.1. It includes various bug fixes around
character encodings, plus Ruby 3.0 and 3.1 support.

The new release is available from Rubygems and Github.

== 1.1 / 2022-05-23

* #588, #577: Sup is now compatible with and tested on Ruby 3.0 and Ruby 3.1.
(Dan Callaghan)
* When the Sup gem installs xapian-ruby, it will install to the user gem
directory if the system gem directory is not writable. (Iain Parris)
* #571: To and From addresses of enclosed messages are now displayed normally,
instead of as Redwood::Person objects. (Iain Parris)
* #570: Fixed wording when displaying enclosed messages without Date header.
(Iain Parris)
* #205, #602: UTF-8 header values are now accepted and handled correctly, as
per RFC6532. (Dan Callaghan)
* #585: Text/plain attachments with invalid charset are now displayed as
US-ASCII (with high bytes replaced) instead of crashing. (Dan Callaghan)
* #424: Spaces are now accepted in RFC2047-encoded header words, even though
the RFC forbids them. (Dan Callaghan)
* Invalid RFC2047-encoded header words are now displayed in their raw form,
rather than trying to forcibly transcode them to UTF-8, as per the RFC's
recommendation. (Dan Callaghan)
* Sup now decodes UTF-7 correctly instead of crashing. (Dan Callaghan)
