Faking a UUID panics

[msorens]

I had a complex struct generating a panic from faker and I isolated it to the uuid field causing the issue.
Here's the minimal code to show the error:

package main

import (
	"github.com/bxcodec/faker"
	"github.com/gofrs/uuid"
	"fmt"
)

func main() {
	var u uuid.UUID
	faker.FakeData(&u)
	fmt.Println(u)
}

And the error trace is:

panic: reflect.MakeSlice of non-slice type

goroutine 1 [running]:
reflect.MakeSlice(0x11367c0, 0x1104fe0, 0x58, 0x58, 0xc420065cc8, 0xc420065cd8, 0x1010068)

This is not possible. See PR #40

This will enable faking UUID in the future.

Not the way you're doing it though, if you have a third party package like that one inside of your struct i would suggest you do

type Herp struct {
 ID uuid `faker:"-"`
}

And then

herp := Herp{}
err := FakeData(&herp)
...
herp.ID =  // use the uuid package manually to create a new uuid

If you use the PR you have to use a

type Herp struct {
 ID string `faker:"uuid_hyphenated"`
}

and then

herp := Herp{}
err := FakeData(&herp)
...
should work.

@DenLilleMand : I like the idea of telling faker to just skip that field, rather than changing it to a string. Had not seen the "skip" annotation in the list of available choices. Thanks!
