feat: ✨ unmarshal into ordered maps

[ghostsquad]

this change will attempt to unmarshal interface{}/any values into an ordered map before falling back to default behavior

resolves #54

[ghostsquad]

I'm converting this to a draft... this needs some more testing

[ghostsquad]

upon testing this in a different project, I've run into this error:

cannot unmarshal map[string]interface {} into Go value of type *orderedmap.OrderedMap[string,interface {}]

there's some more work to do it appears
