add Makie basic recipe

[Moelf]

fix #463

julia> p = Polynomial([1,0,3,4])
Polynomial(1 + 3*x^2 + 4*x^3)

julia> plot(p)

julia> scatter(p)

[Moelf]

one problem is that this doesn't work smartly:

julia> plot(p; axis=(; limits=(nothing, 3, nothing, nothing)))

Awesome!

I'm not sure what to expect in your example with nothing in the limits. Is there something on the Polynomials side we should be doing?

If not, let me know that this is good to merge and I'll merge it in.

[Moelf]

not much, per @asinghvi17 's comments on Slack, we can potentially make a new "full recipe" so that we can inspect the limits of the plot and produce p.(xs) accordingly.

But I think if user is superimposing a polynomial they probably need to manually make xs and poly.(xs) anyway.

I say we can merge.

Great. Many thanks!
