Drop debugger statements

Option: transforms.dropDebugger

What it changes

Removes every debugger statement.

Removing every debugger statement is the point, so this changes behavior.

function foo() {
  debugger;
  return "bar";
}

function foo() {
  return "bar";
}

Run this transform by setting transforms.dropDebugger to true:

obfuscate.mjs

const output = obfuscate(source, {
  transforms: {
    dropDebugger: true,
  },
})

Open the TypeScript implementation on GitHub.

Review behavior checks and cases this transform leaves alone.
