* FastAPI migration:
    - Use pydantic model classes as input parameters to the
      data/calculation classes.
    - Interface field names changed to constructor parameter names (for
      simplicity only during transition, should be updated in a followup
      PR).
    - Add basic interface requirements (e.g. some values > 0, etc.).
 * Update tests for new data format.
 * Python requirement down to 3.9 (TypeGuard no longer needed)
 * Makefile: Add helpful targets (e.g. development server with reload)

 * Add API to sphynx doc (rudimental, due to outdated plugin).
 * Link to swagger.io with own openapi.yml.
 * Commit openapi.json and check with pytest for changes so the
   documentation is always up-to-date.

Add generation of the API documentation for akkudoktoreos
and akkudoktoreosserver packages.

The API documentation is generated by the Sphinx autosummary extension.

 * Dockerfile: Use non-root user, buildx cache, setup for readonly
   container, remove unused apt deps.
   For now don't install pip package and keep development flask server
   as this will be replaced in the future (fastapi). Then a proper
   webserver (e.g. nginx) should be used and the pip package can be
   created and deployed just to the run-stage (with the webserver).
 * docker-compose: Set to readonly (anonymous volumes declared in
   Dockerfile should maintain all writable data).
   Mount config.py for easier development. Should be replaced by
   environment support for all config file variables.
 * Remove unused runtime dependencies: mariadb, joblib, pytest,
   pytest-cov.
 * Move pytest-cov to dev dependencies.
 * Add output_dir to config.py.
 * Fix visualization_results.pdf endpoint.
 * Update docs.

Added documentation. Beware mostly generated by ChatGPT.

The `CacheFileStore` class is a singleton-based, thread-safe key-value store for managing
temporary file objects, allowing the creation, retrieval, and management of cache files.

The utility modules offer a flexible logging setup (`get_logger`) and utilities to handle
different date-time formats (`to_datetime`, `to_timestamp`).

- Cache files are automatically valid for the the current date unless specified otherwise.
  This is to mimic the current behaviour used in several classes.
- The logger supports rotating log files to prevent excessive log file size.
- The `to_datetime` and `to_timestamp`functions support a wide variety of input types and formats.
  They provide the time conversion that is e.g. used in PVForecast.

Improvements for testing of PVForecast
- Use common utility functions to allow for general testing at one spot.
  - to_datetime
  - CacheFileStore
- Use logging instead of print to easily capture in testing.
- Add validation of the json schema for Akkudoktor PV forecast data.
- Allow to create an empty PVForecast instance as base instance for testing.
- Make process_data() complete for filling a PVForecast instance for testing.
- Normalize forecast datetime to timezone of system given in loaded data.
- Do not print report but provide report for test checks.
- Get rid of cache file path using the CachFileStore to automate cache file usage.
- Improved module documentation.

- Add test for PVForecast
- Add test for CacheFileStore in the new cachefilestore module
- Add test for to_datetime in the new datetimeutil module
- Add test for get_logger in the new logutil module

This script automates the integration of multiple GitHub pull requests (PRs)
into a specified integration branch. It fetches each PR, creates a branch
from the PR, rebases the branch onto the integration branch, and then merges
it back into the integration branch. The process is logged to a branch-specific
log file, and if any step fails, the script exits and saves the current progress
(PR number and step) to a branch-specific JSON file. The script can be rerun,
and it will resume from where the last step failed. If the script is run again
on the same branch without providing PR numbers, it will reuse the PR numbers
from the first run.
