Create pyscript to run powerfit browser without server computations

[sverhoeven]

TODO

• block form until pyscript is ready, with loading... modal
• less pyscript
  • use native file input
  • use @when decorator + FormData instead of listeners and getElementById
• use web worker to unblock main UI thread during computation
• show progress, by calling progress func defined in main script in worker.py
• render solutions.out as table
• render fitted model and target density map with molstar, see protein detective visualization notebook
