Inject PureScript compiled code in SFC script block

[klarkc]

We should be able to inject a purescript compiled function in a SFC script block

• [ ] build PureVue.compileScript function which uses purs binary to output javascript code
• [ ] build vite plugin-purevue that compiles using PureVue.compileScript
• [ ] somehow run vite plugin-vue after plugin-purevue compiled purescript to javascript
