Make raw optional on getList

[Bossieh]

I have sequelize afterFind hooks which rely on the instance.get('propertyName') method to read a proprety value. The hooks work fine except on the getList call.

Turns out the raw: true line caused this: https://github.com/lalalilo/express-sequelize-crud/blob/master/src/sequelize/index.ts#L24

An option for example like this would be very helpfull:

app.use(
  crud('/admin/users', sequelizeCrud(User), {
    getListRaw: false
  })
)
