Support for aria-autocomplete (required by Combobox pattern)

[Spone]

The Combobox pattern specifies that an aria-autocomplete attribute should be set on the Combobox element:

The combobox element has aria-autocomplete set to a value that corresponds to its autocomplete behavior:

• none: When the popup is displayed, the suggested values it contains are the same regardless of the characters typed in the combobox.
• list: When the popup is triggered, it presents suggested values. If the combobox is editable, the values complete or logically correspond to the characters typed in the combobox.
• both: When the popup is triggered, it presents suggested values that complete or logically correspond to the characters typed in the combobox. In addition, the portion of the selected suggestion that has not been typed by the user, known as the "completion string", appears inline after the input cursor in the combobox. The inline completion string is visually highlighted and has a selected state.

I don't think this attribute is supported by tom-select yet. Would you consider adding support for it?
