Subject: [PATCH] flake: Add pythermostat to PYTHONPATH in devshell

For easier testing of PyThermostat client code in the development shell,
so that the following is possible right in the repo root:

```
$ python
Python 3.11.9 (main, Apr  2 2024, 08:25:04) [GCC 13.2.0] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> from pythermostat.client import Client
>>> c = Client()
>>>
```
