Cldr Dates Times version 2.20.0

Bug Fixes

• Fix Cldr.Time.available_formats/3 when the locale parameter is a binary.

Enhancements

• Modify the :prefer option of to_string/2 to take a list of preferences. Time formats may sometimes have a :unicode or :ascii preference. Date and datetime formats may have a :default or :variant preference. The :prefer option can now be specified with one or both of these options.
