Shebang support

[asg017]

#!/usr/bin/env -S dataflow run -p 3495 --allow-file-attachments
a = 1

b = 2

c = a + b

similar to deno which is

#!/usr/bin/env -S deno run --allow-net --allow-read
let x = "..."

• [ ] Ignore shebang on:
  • [ ] dataflow run file updates
  • [ ] dataflow format
  • [ ] importing .ojs files
  • [ ] compiling
• [ ] Where should the shebang point to?
  • looks like /usr/bin/env -S does magic here
