Can't dataize integer or float
I think it's necessary to notify users of EO that we can't dataize integer or float like this:
```
[] > app
  5 > @
```
Here is output after `eoc dataize app`:
```
Exception in thread "main" java.lang.ClassCastException: Cannot cast java.lang.Long to java.lang.Boolean
	at java.base/java.lang.Class.cast(Class.java:3605)
	at org.eolang.Dataized.take(Dataized.java:127)
	at org.eolang.Main.run(Main.java:190)
	at org.eolang.Main.main(Main.java:98)
```
Or maybe I do smth wrong?
