This new settings format is not backwards compatible so it would either need to also support the existing format ['123'. '456'], or update or reset the property when the bot is updated.

• If pingRoles.roles is an array, pingRoles.mode is ignored and is always all - equivalent to the current behaviour. Or just use the {if: then} format with the everyone role?
• If pingRoles.roles is not an array (so is an object), dynamic:ly select roles:
  • If pingRoles.mode is all, ping every value where the member has key
  • If pingRoles.mode is highest, find the highest key that the member has and ping its value

Examples:

// always
// -> @123, @456
{
  mode: 'all',
  roles: ['123', '456']
}

// if the member has both 123 and 234,
// -> @456, @567
{
  mode: 'all',
  roles: {
    '123': '456',
    '234': '567',
  }
}

// if the member has both 123 and 234, assuming 123 is higher in the role hierarchy,
// -> @456
{
  mode: 'highest',
  roles: {
    '123': '456',
    '234': '567',
  }
}
