Hello, can u explain, how can im use u'r lib 2 fetch remote screen in realtime?

With OpenSSL 3.0 (which is default since at least Ubuntu 22.04 Jammy), the cipher ECB isn't supported anymore. This will break vncdes#40.

Short reproducer:

> ruby -r openssl -e "p OpenSSL::Cipher::DES.new(:ECB)"
/usr/lib/ruby/3.0.0/openssl/cipher.rb:21:in `initialize': unsupported (OpenSSL::Cipher::CipherError)
	from /usr/lib/ruby/3.0.0/openssl/cipher.rb:21:in `block (3 levels) in <class:Cipher>'
	from -e:1:in `new'
	from -e:1:in `<main>'

Workaround

The current workaround is allowing legacy crypto via openssl.cnf or pin your gem to an older version with selfmade crypto.

If someone have some time, this could be nice to get rid of:

$ bundle exec rspec spec

ruby-vnc tagged 1.1.0 and upload on June 03, 2012 to RubyGems.
This project has merged some commits for long time, but it has not updated in RubyGems yet.
Is it about time to tag 1.2.0 and upload to RubyGems for ruby-vnc gem users!?

＊ please receive pull request #21 before this, I really need this 😁
