Insertion of string enum array #61

Description

I expect no errors while executing the code below, but instead I get panic with interface conversion: interface {} is []main.Address, not []string error on go-clickhouse/ch/chschema/column.go:115.

package main

import (
	"context"
	"fmt"
	"reflect"

	"github.com/uptrace/go-clickhouse/ch"
)

type Address string

type ProblemStruct struct {
	Addresses []Address `ch:"type:Array(String)"`
}

func main() {
	var v = ProblemStruct{
		Addresses: []Address{"1", "2"},
	}

	dsnCH := "clickhouse://localhost:9000/default?sslmode=disable"
	chDB := ch.Connect(
		ch.WithDSN(dsnCH), ch.WithAutoCreateDatabase(true), ch.WithPoolSize(16))

	_, err := chDB.NewDropTable().
		Model(new(ProblemStruct)).
		IfExists().
		Exec(context.Background())
	if err != nil {
		panic(err)
	}

	_, err = chDB.NewCreateTable().
		Model(new(ProblemStruct)).
		IfNotExists().
		Engine("ReplacingMergeTree").
		Exec(context.Background())
	if err != nil {
		panic(err)
	}

	_, err = chDB.NewInsert().Model(&v).Exec(context.Background())
	if err != nil {
		panic(err)
	}

	var got ProblemStruct

	err = chDB.NewSelect().Model(&got).Scan(context.Background())
	if err != nil {
		panic(err)
	}

	if !reflect.DeepEqual(v, got) {
		fmt.Printf("expected: %+v", v)
		fmt.Printf("got: %+v", v)
		panic(nil)
	}
}
