Torch input validation (#149)

* add more kernel dims

* simple test for torch-level shape checks

* add TORCH_CHECK to torch interface

* adds size checking, removes getters and replaces with const attributes.

* adds kernel dims to jit via dict

* replace get_L3_dim with L3_dim

* remove parenthesis

* add a central location for type enums

* add location and type checking. expose LX_dim correctly. Pass types as enums

* pass additional info

* better enum and proper transpose_perm size

* better enum

* better enum

* factor out executables

* rename to shape_test

* add lazy fixtures so that I can easily parameterize tuples. lazy-fixture is un maintained. I can remove in preferred, but it is convenient.

* add enum to torch.dtype

* factor these into their own file for reuse

* added conftest for fixture reuse

* factor out executables

* delete utils.py

* content moved elsewhere

* moved stream test to torch_features level

* wip commit

* retain only core changes

* just forward direction testing, added pytest-subtests to to make testing all the different buffers and buffer dimensions easier.

* return double_backward_rawptrs which got removed accidentally

* add other convs and add permutation where expected

* Some cleanup.

* Cleanup.

* Removed some fixtures that are only used once / reproducibility on generator.

* Light renaming.

* Linted.
