Broken Typescript typings

[pierretasci]

The default typings that were recently added make supporting apexcharts with Typescript near impossible. Many of the options are not nullable by default (end in a ?). For example, the radar option in plotOptions was added but is not nullable. That means in order for Typescript to not complain, I have to define radar options even if that isn't my intended chart type.

I propose that all options be made optional.
