Benchmark available for PTV3?

[mikel-zhobro]

Thank you the nice library!

I am trying to figure out the advantages of WarpConvNet's PTV3 implementation w.r.t the default PTV3 implementation.

1. Is there any benchmarking (memory & time) script for PTV3 or any of its components?
2. when is wp.init() used? For example, in test_attention.py it is used whereas in point_transformerv3.py it is not.

1. There's currently no benchmarking script but should be fairly straightforward to implement.
2. wp.init calls are deprecated and is no longer required
