Chess-graph

Although the eventual goal of this project is to achieve a sunburst chart with shading, custom branching, etc., this release is marked as 1.0 as it includes more than enough to be warranted as a fully functional, production-ready, program.

With this release, the following things are now possible:
- download graph in your supported formats (SVG, PNG, JPEG, WEBP, HTML)
- on hover, see what percentage each slice is of its parent as well as game count
- opening identification - on hover, see what the ECO code + name is for that move path

Requirements and README have been updated. Code has been commented more.

In version 0.9.1, you can download the chart in the following formats:
- png
- jpeg
- webp
- pdf
- svg
- html

To do so, uncomment the lines at the bottom of the code. Make sure you have the requirements fulfilled, they will be stated there.

In this release, you will be able to create a *vivid* sunburst chart with an inputted PGN file. Each first move will have a color assigned to it, and those colors will continue to be passed on to their children.

This release is fully functional. However, I am working on a color-coded opening where the pie slices will be shaded based on whether black or white wins more often. That will be released in version 1.0 (coming soon).
