fix: packaging type info

[alespour]

Closes #622

Proposed Changes

This adds PEP 561 distributing and packaging type information, which specifically resolves issue with MyPy
error: Skipping analyzing "influxdb_client": module is installed, but missing library stubs or py.typed marker [import-untyped]

The required marker really is just an empty file py.typed. The same fix has been applied in v3 client.

Hi, for some reason installing the package with the latest version (1.43) from pip does not install the py.typed file. Steps to reproduce:

python -m venv venv
. venv/bin/activate
python -m pip install influxdb_client
ls -l venv/lib/python3.11/site-packages/influxdb_client | grep typed
# Nothing

Installing directly from the repo works though (pip install git+https://github.com/influxdata/influxdb-client-python).
Thanks
