New features for adding more grid lines to the Radar Chart

Hello there! I created a separate file called ggradar2.R, where I reused the code from ggradar.R with the intention of adding more grid lines to ggradar, which originally had only three of them.

In this new 'ggradar2' branch, I added four grid lines between grid.max and grid.min, totaling 6 grid lines. The grid lines follow the following order (min, n2, n3, n4, n5, max).

I also added some features to change the colors and the vertical offset of the grid lines' labels.

Here are some results:

Radar chart with 6 grid lines.

Radar chart with 5 grid lines with labels positioned at the top of them.

Radar chart with 6 grid lines and multiple groups.

It is also possible to reproduce the default radar chart of ggradar, with 3 grid lines.
