Use of deprecated np.int in dimension type checking

[Bronzila]

Here the deprecated np.int type of numpy is used, when initalizing DEHB without a configspace object. This is deprecated since numpy v1.20 and should be replaced by either np.int32 or np.int64.

Hey @Bronzila I will make these required changes. Can you assign me this issue?

Will add that the deprecation is mostly when used with np.method(..., dtype=np.int) as this is now made equivalent to np.method(..., dtype=int) and the latter should be preferred. In the case you've shown there, the best way to do instance checking right now is isinstance(x, (int, np.integer)). (Likewise you have np.floating super classes np.float32/64)

@SandboxHead I will do so, thanks.
It would be great if you could have a look at our contributing guidelines. Since this is currently just a draft, it is not merged to master yet, however it should still be a good guidance.
