Is there a way to set the transparency of the filled band plots from `Makie.jl`? For example, what option can I add onto `band!` in the following code to give transparency, similarly to `fillalpha` in `Plots.jl`?

```julia
using CairoMakie
f = Figure()
Axis(f[1, 1])
xs = 1:0.2:10
ys_low = -0.2 .* sin.(xs) .- 0.25
ys_high = 0.2 .* sin.(xs) .+ 0.25
band!(xs, ys_low, ys_high)
band!(xs, ys_low .- 1, ys_high .-1, color = :red)
f

```

I tried the attributes listed at [band](https://makie.juliaplots.org/stable/examples/plotting_functions/band/index.html) but none of them see to relate to the opacity.

A tuple like `(:red, 0.5)` can be used as a shorthand for a transparent color.
