go-singleton: Generic singleton factory

Starting from go1.18, Go will officially support generic. This package is designed to embrace the new technic for convenience.

Call Singleton with a given type name to get a pointer to this type.

type MyType struct {

}

v1 := singleton.Singleton[MyType]()
v1.field = 123

v2 := singleton.Singleton[MyType]()
println(v2.field) // Output: 123
