func (Compiler) CompileContext(ctx context.Context, loc string) (*Schema, error)
// MustCompile omitted as it seems less useful with a context
func (Compiler) RegisterLoaderContext(loader URLLoaderContext)

type URLLoaderContext interface {
	// This could also still just be Load().  there shouldn't be a use case to support both Load and LoadContext. 
	LoadContext(ctx context.Context, url [string](https://pkg.go.dev/builtin#string)) ([any](https://pkg.go.dev/builtin#any), [error](https://pkg.go.dev/builtin#error))
}
```

Internally the `defaultLoader` would always use the context version.  `RegisterLoader()` would just then wrap a URLoader with one that adds a default context.Background() by default
