Chart.js Allow each bar in a bar chart to have a different width

Feature Proposal

Currently, the barThickness option only takes a single number as input. If we could pass in an array, then each bar could have its own width.

This is similar to properties like backgroundColor and borderColor, which can take a single value or an array of values for each point in the dataset.

Feature Use Case

I'd like to make a bar chart where the width of the bar indicates the "size" of that category (the y-axis measures an average of all points in that category).
