Primitive Types does not contain Float

[SamN2997]

Hello,

We've just noticed that the primitive types do not support float (https://github.com/marazt/object-mapper/blob/9d62e9bf00cd78afdaccd6e950a6bb4a1dd1cc06/mapper/object_mapper.py#L18).

This is currently raising an exception when using float types.

Is there any plans to support floats in the future?
