- update to 3.0.25:
* Fix handling of 'config file does not exist' when embedding
ptpython.
* Don't show "Impossible to read config file" warnings when no
config file was passed to `run_config()`.
* Output printing fixes:
* Paginate exceptions if pagination is enabled.
* Handle big outputs without running out of memory.
* Asyncio REPL improvements:
* From now on, passing `--asyncio` is required to activate the
asyncio-REPL.
* This will ensure that an event loop is created at the
start in which we can run top-level await statements.
* Use `get_running_loop()` instead of `get_event_loop()`.
* Better handling of `SystemExit` and control-c in the async
REPL.
