Faster builds using Sucrase

🙋 feature request

Sucrase is about 20x faster than Babel. Here’s one measurement of how Sucrase compares with other tools on a large TypeScript codebase with 4045 files and 661081 lines of code:

             Time      Speed
Sucrase      2.928s    225752 lines per second
swc          13.782s   47966 lines per second
TypeScript   39.603s   16693 lines per second
Babel        52.598s   12569 lines per second

🤔 Expected Behavior

Use Sucrase instead of Babel

😯 Current Behavior

We are forced to use babel

💁 Possible Solution

Use a dedicated plugin instead of using babel.

Parcel now uses swc instead of Babel which is also used for the scope hoisting transforms, which wouldn’t be possible with Sucrase.
