New functionality
- 26 Added `Qpivot` Primitive
- Thanks AmyRouillard
- 27 Plot hypergraphs
- Thanks metalcyanide
- 28 Specify Qiskit unitaries with strings
- Thanks khnikhil
- `utils.plot_circuit` new minimal circuit plotter
- `utils.get_tensor_as_f` new tensor contraction function for naive QC simulation
- Reworked `Qmask` and added `Qunmask` which inherits from a new `Qsplit` primitive
- Added `*` and `!` wildcards to generate string patterns
- Added custom execution for `Qhierarchy.__call__ ` to enable use without 3rd party packages and classical algorithms
- Added option to specify symbol function `Qmotif.symbol_fn` to parametrize gates based on edge order

What's new

- N-qubit unitary support (hypergraphs)
- Renamed primitives (Qconv->Qcycle, Qpool->Qmask, Odense->Qpermute, Free->Qinit)
- New Qunmask primitive
- New Qunitary class to manage arbitrary functions
- Functionality to Convert any level motif into Qunitary
- Support for providing sub motif as mapping for higher level motif
- More pattern support for Qmask/Qunmask (undo previous), wild cards, binary strings
- Removed networkX as dependency (refactored plotting of motifs)
- New tutorial, single notebook for 3 frameworks (qiskit, cirq, pennylane)
- New examples notebook
- Edge order hyperparameter for Qmotif
- Various small fixes

Note Version 0.4.0 is not backwards compatible.
