Title: Adds an option to inset the legend.

To use — set the position to “inset”. Then, configure the inset
position by setting anchor to “top-left, top-right, bottom-left, or
bottom-right”, and offset x and/or y.

For example:
legend: {
position: "inset",
inset: {
anchor: "top-left",
x: 20,
y: 20
}
}
