Add point to a series of a higchartProxy object

hcpxy_add_point(
  proxy,
  id = NULL,
  point,
  redraw = TRUE,
  shift = FALSE,
  animation = TRUE
)

`proxy`	A `higchartProxy` object.
`id`	A character vector indicating the `id` of the series to update.
`point`	The point options. If options is a single number, a point with that y value is appended to the series. If it is an list, it will be interpreted as x and y values respectively. If it is an object, advanced options as outlined under series.data are applied
`redraw`	Whether to redraw the chart after the point is added. When adding more than one point, it is highly recommended that the redraw option be set to false, and instead Highcharts.Chart#redraw is explicitly called after the adding of points is finished. Otherwise, the chart will redraw after adding each point.
`shift`	If `TRUE`, a point is shifted off the start of the series as one is appended to the end.
`animation`	Whether to apply animation, and optionally animation configuration.
