Add Plot.limit method

[mwaskom]

I still feel slightly non-committal about this having its own distinct method, but I think this is probably the most straightforward approach.

This has the nice feature of accepting and converting various units, including on a Nominal scale:

(
    so.Plot(diamonds, "price", "clarity")
    .add(so.Scatter(), move=so.Jitter(.8))
    .limit(x=(0, 20000), y=["VS1", "SI2"])
)

Closes #2871
