[Fixed]

• CVE-2025-40918 (Insecure source of randomness),
  required addition of dependency on Crypt::URandom
  [Changed]
  
• Modules Authen::SASL::Perl::CRAM_MD5, Authen::SASL::Perl::DIGEST_MD5
  and Authen::SASL::CRAM_MD5 marked as deprecated based on the respective
  RFC documents; thanks to @robrwo for the suggestion and @neustradamus
  for the pointers to the documentation
  
• Update module metadata to point to the new 'perl-authen-sasl' org
  on GitHub to which the modules moved
  
• Use VERSION declarations in 'package' statements, since our minimum
  Perl version is 5.14 anyway
