fix: prevent UI blocking during 333 solver initialization

[bryanlundberg]

What does this PR do?
the initialization of the 333 cross & xcross solver was blocking the UI thread. By offloading the initialization process to a web worker, we ensure that the UI remains responsive during this operation.

issue: (interface respond until finish initializing process)

after: (interface keeps responsive while initializing process) [simulate 5 sec delay loading]
