Subject: Galilean PSATD: current correction and rho-free formulation (#1151)

* Introduce option to update E with/without rho

* Clean up

* Implement current correction for Galilean PSATD (needs bug fix)

* Include equations in docs

* Fix EOL whitespaces error

* Small clean-up

* Implement Galilean PSATD update without rho

* Clean up

* Fix bug in current correction

* Fix EOL whitespaces

* Clean up

* Fix unused import

* Remove unused variable

* [skip CI] Improve docs

* Clean up style

* Fix EOL whitespaces

* Fix EOL whitespaces

* Clean up style

* Revert analysis script to old status

* [skip CI] Clean up style

* Make equations more human-readable and improve comments

* 2D test with current correction works

* Temporary build fix as in #1197

* 3D test with current correction works

* Rename th and th_star as theta and theta_star

* Fix a couple of wrong comments

* Add vertical spaces to improve readability

* Improve documentation

* Function CurrentCorrection is now pure

* 2D benchmark fields data are now correct

* Add limits of coefficients for nu=-1

* Change default of update_with_rho for Galilean PSATD
