Tja2fumen

What's Changed

* Properly set timing window values for easier difficulties by vivaria in https://github.com/vivaria/tja2fumen/pull/74
* Allow `tja2fumen` to be run on folders to allow fixing timing windows on all .bin files by vivaria in https://github.com/vivaria/tja2fumen/pull/75

This patch release fixes a small but important bug introduced in version 0.7.0 that caused conversion failures when combined with TakoTako:

- [Don't throw error if file extension is not `.tja`](https://github.com/vivaria/tja2fumen/commit/ade4f66679b52ce06248c913578c511d3fda8aab)

Moving forward, I will explicitly test compatibility with TakoTako's `TJAConvert.exe` before creating a new release. My apologies for any inconvenience this has caused.

> [!WARNING]
> tja2fumen 0.7.0 and 0.7.1 include a small bug that causes conversion failures when used with TakoTako. Please upgrade to 0.7.2. The releases for versions 0.7.0 and 0.7.1 have been marked as 'Prerelease' for this reason.

This patch release includes many small improvements to avoid unnecessary crashes due to chart errors. Now, instead of crashing, `tja2fumen` will try to fix issues where it can, and alert the user with detailed warning messages.

For the full changelog since 0.7.0, please refer to [this link](https://github.com/vivaria/tja2fumen/compare/0.7.0...0.7.1).

Includes the following fixes:

- Don't cluster isolated 4th notes.
- Include big notes (大) in clusters (so that, for example, ddddD will be ド ド ド ド ドン(大) and not ド ド ド ドン ドン(大)
- Group mixed sets of dense notes together (12th, 16th, 18th, 24th, 32nd, 36th, etc.)
- Don't use "don" or "katsu" for dense groups of 4 (in other words, use only do/ka)
