ConvTranspose2d Operator

[Coderitter-GmbH]

First Implementation of the ConvTranspose2d Operator. Its not support every combination of parameters but it passes the most tests.

fixes #79

Thanks for the PR! I noticed a few things and commented accordingly.

I still have to:

• remove the unused function
• use op_ctx
• use trace

To use default_dilations, default_pads and default_strides I have to allocate memory. Doesn't that cause memory leak, because later I don't know if op_ctx->pads contains the pointer from a_pads->ints or my self allocated memory (ARRAYDUP)

you have multiple options to solve this:

• always dup
• mark dup as dup with extra flag or set to NULL to use onnx one
• compare pointers when freeing

I think I would some day prefer the comparison, since it's simple and moves the annoying stuff into the free function but atm I would simply dup everything. we can always start from there for optimizations, especially since the free function is not utilized at this point

Okay dup everything it is for now

Can you look over it again?

[Coderitter-GmbH]

That should be it
