Feature request: Make namespace in ts file optional

[Ferikl]

Hi Spatie! Thanks for amazing package.
I have some issue with generated ts file - our fe guys wants all entities be w\o namespaces.

Something like:

typescript-transformer.php

...
   'preserve_namespaces' => true/false,
.....

Please add this feature
