Operator attributes tested by opset

Context

Imported operators from ONNX do not consider most opset/versions of said operator. Accepting or ignoring attributes not supported in Aidge and causing errors

Modified files

TODO detailed explaination in general: added conditions to check for opsets and its corresponding attributes. In case of not expected attributes a warning is emmited and an identity operator is created instead.

TODO

operators:

• add
• averagepool
