Commit Message

Add TypeScript emit for boolean expressions and arrays

Since Lukas and I need to figure out more of what this language will
look like and how sema will actually work with Haskell, in the meantime
I am adding some more TS codegen code.

I realized one problem is how to translate a code like `if x { a } else { b }`,
which is a valid expression in GB but not in TS. I think the best
translation for this is the IIFE

```typescript
(() => { if (x) { return a; } else { return b; } })()
```

This way, we don't have to create and keep track of local variables
created in the local scope.

However, this warrants discussion of how blocks in GB actually look
like. I think we decided that blocks that end with a statement (like
`{ foo! }`) evaluate to the unit type, and blocks that end with an
expression evaluate to that expression. The translation would be finish
voidly and return the relevant expression, respectively.
