This adds back a function available in 3.x: exporting the GDScript files in a binary form by converting the tokens recognized by the tokenizer into a data format. It is enabled by default on export but can be manually disabled. The format helps with loading times since, the tokens are easily reconstructed, and with hiding the source code, since recovering it would require a specialized tool. Code comments are not stored in this format. The `--test` command can also include a `--use-binary-tokens` flag which will run the GDScript tests with the binary format instead of the regular source code by converting them in-memory before the test runs.
