v1.1.0

Small updates to the API, but no changes to the actual Argon2 capabilities

• Argon2Kt no longer exports extension functions. Instead they are now available as "static" members of the Argon2KtUtils class.
• The previous Argon2KtUtils which dealt with finding iteration counts has been renamed to Argon2KtBenchmark.
• Android dependencies were updated and experimental feature usage removed.
