Move try it out to a web asm project

[stevehalliwell]

While building ulox in unity try it out is a fun exercise, it's not the nicest code editor or the easiest to layout.

If straight forward, consider creating a webasm app that runs the ulox tryitout.

Initial test with manually created hello world demo in blazorwasm, is extremely promising.

There's non trivial rework of how test and sample scripts get to the try it out but doable. Similarly a better text input is most likely very much in reach.
