Create confidence envelopes from a `uhc_data_frame`

Simplifies sampled distributions in a uhc_data_frame to confidence envelopes

conf_envelope(x, levels = c(0.95, 1))

`x`	`⁠[uhc_data]⁠` An object of class `uhc_data_frame`, as returned by the function `as.data.frame.uhc_data()`.
`levels`	`⁠[numeric]⁠` A numeric vector specifying the desired confidence levels. Defaults to `c(0.95, 1)` to create 95% and 100% confidence intervals.

This can dramatically improve plotting time for UHC plots by simplifying the many sampled lines down to the boundaries of a polygon.

Returns a data.frame with columns:

var: The name of the variable
x: The x-coordinate of the density plot (the value of var).
label: If var is a factor, the label for the value given by x.
U: The y-coordinate of the density plot for the use distribution.
A: The y-coordinate of the density plot for the availability distribution.
⁠CI*_lwr⁠: The lower bound of the confidence envelope for the corresponding confidence level.
⁠CI*_upr⁠: The upper bound of the confidence envelope for the corresponding confidence level.
