Update code to be compatible with jax 0.4.38

• fix calls to WrappedFun and lu.transformation
• add hash to Tracer
• add to_tangent_aval

v0.0.7

Adapt with latest jax changes

v0.0.6

Add braket operator.

braket(f, g) is equivalent to o.integrate(o.numpy.conj(f) * g).

However, the former is preferred because currently if we use functional gradient

jax.grad(lambda f: o.integrate(o.numpy.conj(f), f))

It somehow results in redundant computation paths that is not optimised away by XLA.

v0.0.5

Fix the data type for nabla

Changelog

• Fix support for python < 3.11
• Minimize dependency

v0.0.3

First release without big glitches.
