Add (Known) Local Optima of Smoof Functions to Gradient Field Heatmap.

If the underlying single-objective functions are smoof-functions, extract their local optima and add them to the gradient field heatmap.

addGGOptima(g, fn1, fn2, fn3, symbol1 = 21L, symbol2 = 22L, symbol3 = 24L, ...)

`g`	[`ggplot2::ggplot`] `ggplot`-object as created by `ggplotHeatmap`.
`fn1`	[`function`] The first objective used for computing the multi-objective gradient.
`fn2`	[`function`] The second objective used for computing the multi-objective gradient.
`fn3`	[`function()`] The third objective (if existing) used for computing the multi-objective gradient.
`symbol1`	[`⁠[integer](1L) \| [character](1L)⁠`] Symbol used for indicating the local optima of the first objective (default: `21L`, i.e., a filled circle).
`symbol2`	[`⁠[integer](1L) \| [character](1L)⁠`] Symbol used for indicating the local optima of the second objective (default: `22L`, i.e., a filled square).
`symbol3`	[`⁠[integer](1L) \| [character](1L)⁠`] Symbol used for indicating the local optima of the third objective (default: `24L`, i.e., a filled triangle).
`...`	any Further arguments to be passed to the `geom_tile` function of `ggplot`.
