It does not work if numbers are included in the package path

Thank you for creating a good tool for DDD.
I think it will be very helpful.
But It can not be generated well if numbers are included in package path as the following .
In my case I used numbers for versioning.

package example

import (
	"encoding"

	"github.com/hoge/fuga/v1/proto"
)

//go:generate go-genaccessor

type Person struct {
	id         string                 `getter:""`
	name       string                 `getter:"" setter:"Rename"`
	tags       []string               `getter:"" setter:""`
	text       encoding.TextMarshaler `getter:"" setter:""`
	personType proto.Type             `getter:"" setter:""`
}

// Code generated by go-genaccessor; DO NOT EDIT.

	"encoding"
