/**
 * Validates a filter comparison operation and its sub-operation.

 * @param {UITypes} uidt - The UI type to validate against.
 * @param {any} op - The main comparison operator.
 * @param {any} [sub_op] - The optional sub-operation.
 * @param {FilterParseError[]} [errors=[]] - An optional array to collect errors.
 * @returns {FilterParseError[]} - An array of validation errors, empty if no errors.
 *
 * This function checks if the given `op` is a valid comparison operator and, if a `sub_op` is provided,
 * ensures it is compatible with the given `uidt`. If any validation fails, errors are added to the array
 * and returned instead of throwing an exception.
