v0.7.0

Breaking:

• The options argument can no longer be None. Use Options(0) instead.
• pyromark.events now uses pythonize Rust crate, the output will be different and more correct.
• The only exported member of pyromark.event is now Event.

Feature:

• Support for the --output flag in the CLI.
• Backport __str__ and __format__ behavior for pyromark.Options from Python 3.11.

Fix:

• Ensure that the input file is always closed in the CLI.
