Actual behavior:
@isin validation type described like it allowed only for string[][] type

Expected behavior:
But should allow for numbers also too. It was fixed in validator that sequelize use:
validatorjs/validator.js#185
validatorjs/validator.js@5c4cbf7

Do not to see any reasons to limitation here.
