I think it's better to keep the cls name convention maybe.

Ah yes good find 👍 I think subtype is probably better than cls here and also for create_cell_with_type in that case!

Fixes #947.
As documented, we have to call
subtype->tp_alloc(subtype, nitems)in tp_new.In this PR, I also renamed
PyClassAlloc::alloctonew, since it does not actually overridetp_alloc.
