Missing Type Annotations

There are missing type annotations for some functions in this library.

The `typing` module does not exist on CircuitPython devices so the import needs to be wrapped in try/except to catch the error for missing import. There is an example of how that is done here:

```python
try:
from typing import List, Tuple
except ImportError:
pass
```

Once imported the typing annotations for the argument type(s), and return type(s) can be added to the function signature. Here is an example of a function that has had this done already:

```python
def wrap_text_to_pixels(
string: str, max_width: int, font=None, indent0: str = "", indent1: str = ""
) -> List[str]:
```
If you are new to Git or Github we have a guide about contributing to our projects here: https://learn.adafruit.com/contribute-to-circuitpython-with-git-and-github

There is also a guide that covers our CI utilities and how to run them locally to ensure they will pass in Github Actions here: https://learn.adafruit.com/creating-and-sharing-a-circuitpython-library/check-your-code In particular the pages: `Sharing docs on ReadTheDocs` and `Check your code with pre-commit` contain the tools to install and commands to run locally to run the checks.
