A map that supports default values.

## Basic Example

```go

import (

	"fmt"

	"github.com/spenserblack/go-defaultmap"

)

m := defaultmap.NewMap[string](func() string { return "I'm the default!" })

m.Insert("exists", "Hello, World!")

fmt.Println(m.Get("exists")) // Hello, World!

fmt.Println(m.Get("doesn't exist")) // I'm the default!

fmt.Println(m.GetOr("also doesn't exist", "I'm a one-time default!")) // I'm a one-time default!

```
