Minibudget

This release changes the version to require Python 3.12 to avoid issues where fstrings with internal quotes are not parsed correctly.

This version adds an html output option for `minibudget diff`. This might be helpful if (like me) you want to use minibudget as part of a pipeline for tracking budgeted vs actual expenses.

This release adds the ability to generate charts using `minibudget chart` and implements sunburst charts for expenses.

It also switches to calendar versioning in the format `YYYY-MM-R`. This is the first release in November 2024 so it's `v2024-11-1`. The next release is likely to be `v2024-11-2`. This is so I can deliver rolling releases up to `pip` whenever something useful is part of the project, regardless of how big or small the feature is, without rapidly growing release versions up to `0.151.0` or other overblown numbers.

This release adds a CSV output option for diffs.

This version updates the README with instructions on how to install via `pipx`.
