Jamstats

There's a gap in version numbers since the last release, because I needed to test fixes to the Pypi distribution of JamStats by releasing them, but those fixes made no difference to JamStats functionality (Issue 175).

This release also fixes Issue 177, which was matching skaters up with the wrong penalties (but the correct number of penalties) on the skater penalty plot.

In this release:

* Removed a dependency on the dead package `attrdict` that caused incompatibility with Python 3.10+
* Fixed some problems with automatic web client refreshing that probably didn't affect all users

This release fixes bug 166, a problem with empty color strings occurring in the JSON file, that *seems* to have crept in in a recent CRG version (since it was reported twice in one week). It also adds some defensive coding against other possible plotting errors.

This release fixes Issue 159 , a problem that stopped the Windows executable from working on Windows 10.

v1.4.0 adds the ability to download the JSON file representing the game state, at any time, from the web interface. That's in a link in the left sidebar, down low.

Also, I'm giving a better error message if there's a problem processing the game JSON in some way (e.g., a chart fails to build), and asking the user to download the JSON file and upload it to a new github issue.

This will give users some recourse when they encounter issues like 156 .

This release mostly represents a reorganization of code, and contains a few changes to some plots.
