v1.13.0

This release includes the changes from the PR: #64 gomodifytags handles now the following cases:

• anonymous structs as function parameters

func test(arg struct {
 	Field int `json:"field"`
 }) {
 }

• "pointer to struct" type declaration

var x *struct {
 	Field int `json:"field"`
 }

• "array of struct" type declaration

var x []struct {
 	Field int
 }

and nested variants : "array of pointers to array of structs".
