Cyclomonitor

* New dependency: `aiofiles`
* This is used by `atcf` and `ibtracs` so disk writes are not blocking
* Fix: Automatic routines actually restart on reconnect
* Fix: NameError in `cli.present` and in `atcf.get_forecast` when getting NHC forecasts
* Changed: Full IBTrACS update now runs once per month instead of once per year
* Changed: `atcf.WrongData` and `atcf.NoActiveStorms` now inherit from `atcf.ATCFError`
* Changed: CLI start-up message is now hidden when `stdin` is a pipe.

* Change: Try to accomodate for recent dissipations when considering whether or not to suppress an automatic update
* Fix: Fix desynced lists in the get_forecast command when the last update was from the main source
* Removed: Warning message on CLI startup removed since it's not longer relevant

* Fix: Fix [3](https://github.com/ntvmb/cyclomonitor/issues/3)

* Added: CLI now supports user-defined variables
* Fix: CLI now works on Python <3.11
* Known issue: ATCF commands can break ([3](https://github.com/ntvmb/cyclomonitor/issues/3))
* Changed: ibtracs no longer depends on the `sqlite3` shell

* Added: Command-line interface
* Run the CLI with `python3 -m cyclomonitor.cli`. Type `help` for commands

* Added: `/server` command
* Set the invite through the `server` config parameter
