[JS] Test JS bundle using parcel

Currently it can't handle importing like (it can't find map.ts)
```java

import {...} from "apache-arrow"
```
Also
```java

import {...} from "apache-arrow/src/Arrow.ts"
```
doesn't work (because it's referring to JS files in the distribution, while the source should refer to .ts files).

While the error might be a parcel bug / quirk, how it resolves the paths, we still might to support it's latest versions.

Start by reproducing the two failing imports with the current Parcel version, including the missing map.ts resolution and the apache-arrow/src/Arrow.ts case. Compare how Parcel resolves source TypeScript files versus distribution JavaScript files; done means the JS bundle test passes for both import forms.
