Updes

This release includes:
- A patch to fix the problem that occurred due to non-staking of the field arguments when passed to the differentiable operators
- Separate readmes for PyPI and GitHub
- Nicer documentation with 3 pages and a longer tutorial

Finally, Updes is available in its first official release. This release comes with:
- A way to simulate and control PDEs with ease
- A documentation with QuartoDoc
- Detailed readme and reference paper
- Further example PDEs in the demos
- Etc.

We are officially accepting issues and pull-requests 🎉

Major pre-release before first official release !

Miles stone reached.
Periodic boundary conditions !

This release focuses on demos for the Navier-Stokes test case:
- Derivation of various schemes for the NS equations
- Training PINNs and collecting performance metrics
- Benchmarking CPU times and peak memory usage
- Etc.

This release focuses on providing accurate examples on how to use Updec:
- Formulation of the adjoint equations for Laplace
- 3 different formulations of the adjoint equations for Navier-Stokes (the best has a negated loss)
- Find appropriate hyperparams for differentiable solvers on Navier-Stokes for better memory efficiency
- Implements finite difference in lieu of the differentiable solver on Navier-Stokes
- Integrated Adam optimiser to DAL and DP gradient descents
- Improved plotting, small bugs, etc.
