`geom_col()` with categories on vertical axis does not render correctly

[christophscheuch]

I'm using plotnine version 0.14.5. The following code

from plotnine import ggplot, aes, geom_col, coord_flip
from plotnine.data import mtcars

(ggplot(mtcars, aes(y = "factor(gear)", x = "mpg"))
    + geom_col()
)

produces this figure

However, we should expect this:

which I created using coord_flip():

(ggplot(mtcars, aes(x = "factor(gear)", y = "mpg"))
    + geom_col()
    + coord_flip()
)

I noticed this issue in a more complex project and created this reprex for illustration.

This is expected because at moment plotnine geoms are not yet aware of their orientation.
