Is there any plan to support "binding" struct tag for Bind() method?

Echo is awesome in its own way and I don't want to compare it to another framework. But I'd like it to adapt the `binding` tag in Gin:
```
type Login struct {
    User     string `form:"user" json:"user" binding:"required"`
    Password string `form:"password" json:"password" binding:"required"`
}
```
If you send a payload with empty `User`, the binding will fail.
