🔖 Release v0.4.0

[nevans]

This release is loooong overdue. Here's what I see remaining:

Deprecations:

• 🗑️ Deprecate backward compatible parameters to new and starttls #175
• ✨ Minor updates to SASL::Authenticators API #184 (removes some unreleased API without warning)

Bugfixes:

• 🐛 Fix empty SASL-IR to send "=" #180
• 🐛 Fix authenticate using Symbol mechanism name #186
• Net::IMAP::ResponseParseError: unexpected token NUMBER (expected SPACE) #189
• NoMethodError: undefined method `[]' for nil:NilClass #190
• ResponseParseError in envelope: unknown token - #{???} #191 not new; fix after v0.4.0

After looking into it more closely, #191 doesn't appear to be new. It's coming from invalid server responses. So a workaround can wait until after v0.4.0, in my opinion.
