Remove Operator reference to Tensor

See merge request !46

- Remove setInput in Node
- Change setDatatype to setDataType in GraphView and Tensor binding
- Add namespace comment
- Update Node includes
- Run forwardDims() only if operators use Tensors

[Fix] set FC/ConvDepthWise parameter sizes at construction by adding the number of input channels in construction parameters

[FIX] MetaOperator output was badly linked to its children.

See merge request !52

Ignored inconue node types by creating a spesific branch of the FSM that cancels the transition

See merge request !51

- Change parent class from Operator to OperatorTensor
- Remove shared and not customed functions from operators
- Uniformize operators behaviour:
    - inputs are set to nullptr at initialization by default
    - parameters whose size can be computed at initialization are (FC, ConvDepthWise)
    - Many more checks in functions with AIDGE_THROW_OR_ABORT()

- Add a common parent class to each Operator using Tensors: OperatorTensor
- Gather shared operator functions in OperatorTensor
- Add generic mInputs and mOutputs attributes for OperatorTensor
- Add an enum to identify the type of Data used by each Operator
- Change Inputs, DataInputs, Outputs for Inputs, Data, Attr, Outputs for less confusion

Add feature/graph regex/query resolution
