building anymap on nightly rust now triggers a future incompatibility warning, here's a copypasted terminal output

The package `anymap v1.0.0-beta.2` currently triggers the following future incompatibility lints:
> warning: adding an auto trait `Send` to a trait object in a pointer cast may cause UB later on
