bra-ket-vue for visualizing state and transition matrix

[stared]

• [x] imports bra-ket.vue 0.1.0, https://github.com/Quantum-Game/bra-ket-vue
• [x] uses KetViewer
• [x] uses MatrixViewer
• [x] basic interaction

On bra-ket-vue side:

• [x] type exports (now we get errors here in Vutur, but it still wokrs)
• [ ] better color and size for KetViewer
• [x] emitting column index vector in MatrixViewer

Now things transition matrix work also for diagonal and circular bases!
