byteArrayPreferencesKey
Get a key for an ByteArray preference. You should not have multiple keys with the same name (for use with the same Preferences). Using overlapping keys with different types can result in ClassCastException.
Note: ByteArrays returned by DataStore are copies. Mutating their state will do nothing to the underlying data store. They must be set explicitly.
Return
the Preferences.Key
Parameters
name
the name of the preference
