Add option to remove only binary or whole directory

Currently, binary-install assumes that uninstalling should remove the entire directory from the user's machine, however some libraries may have application-specific code in that directory. If that is the case, they may want to give users the choice of whether or not they want to remove application-specific code, or just the binary.

binary-install should remove the entire directory by default, but should allow library consumers to toggle the feature where the user is prompted to either remove the entire directory or just the binary.

current code in uninstall that should remain the default

if (existsSync(this._getInstallDirectory())) {
  rimraf.sync(this.installDirectory);
  console.log(
    `${this.name ? this.name : "Your package"} has been uninstalled`
  );
}

if the user passes option.uninstallPrompt = true

"Would you like to remove all of your data associated with ${this.name}`? (y/n)

if y -> use existing default code

if n -> fs.unlink(this._getBinaryPath())

Start at the uninstall entry point and inspect the existing checks around _getInstallDirectory(), installDirectory, and _getBinaryPath(). Preserve the current full-directory removal as the default, then verify that option.uninstallPrompt controls the choice and that declining removes only the binary.
