1.4.1

Enhancements

• unify much functionality from 1D, 2D and 3D into general arbitrary geometry
  class :class:quimb.tensor.tensor_arbgeom.TensorNetworkGen
• refactor contraction, allowing using cotengra directly
• add :meth:~quimb.tensor.tensor_core.Tensor.visualize for visualizing the
  actual data entries of an arbitrarily high dimensional tensor
• add :class:~quimb.tensor.circuit.Gate class for more robust tracking and
  manipulation of gates in quantum :class:~quimb.tensor.circuit.Circuit
  simulation
• tweak TN drawing style and layout
• tweak default gauging options of compressed contraction
• add :meth:~quimb.tensor.tensor_core.TensorNetwork.compute_hierarchical_grouping
• add :meth:~quimb.tensor.tensor_core.Tensor.as_network
• add :meth:~quimb.tensor.tensor_core.TensorNetwork.inds_size
• add :meth:~quimb.tensor.tensor_core.TensorNetwork.get_hyperinds
• add :meth:~quimb.tensor.tensor_core.TensorNetwork.outer_size
• improve :meth:~quimb.tensor.tensor_core.TensorNetwork.group_inds
• refactor tensor decompositiona and 'isometrization' methods
• begin supporting pytree specifications in TNOptimizer, e.g. for constants
• add experimental submodule for new sharing features
• register tensor and tensor network objects with jax pytree interface
  (:pull:150)
• update CI infrastructure

Bug fixes:
