v0.3.0

Added

• [breaking] make the studio a Tauri app with a 3D view, and the photonoxide program (#36)
• open the studio's start page with a bare photonoxide, and release binaries (#38)
• add a multilayer stack's reflection and transmission of a plane wave (#40)
• add 2D FDFD with stretched-coordinate PMLs and its exact power flux (#41)
• add 2D FDFD ports: the grid's own modes, one-way sources and a reciprocal S-matrix (#42)
• reuse an FDFD matrix's symbolic analysis across a sweep (#43)
• add an fdfd job: a device on one layer by 2D FDFD with ports, live in the studio (#44)
• add adjoint gradients for 2D FDFD, checked against finite differences (#45)
• add Hadley's high-accuracy interface and corner equations as a full-vector mode solver (#47)
• add 3D FDFD on the Yee grid with stretched-coordinate PMLs (#46)
• add a QMR iterative solver for 3D FDFD, on the curl-curl operator or Shin and Fan's (#48)

Fixed

• (fdfd) put Shin and Fan's ε⁻¹ at the nodes, inside the gradient (#50)

Documentation

• reshape the roadmap around components, circuits and active photonics (#49)
• mark 0.2 and 0.3 done in the roadmap (#51)
