Make a default PATH_PROVIDER to write to tmp if one if not provided

With the development of using numtracker for a path provider we would want a default path provider to exist for if people don't set one. This is with the idea that blueapi will control the path provider going forward. We need to discuss how we want to go forward with this.

```
PATH_PROVIDER: PathProvider = StaticPathProvider(UUIDFilenameProvider(), "/tmp")
```
