Create a ojo_scales() function that will automatically format the scales with defaults based on variable names

[andrewjbe]

I'm envisioning this working along the lines of:

my_data |>
   ggplot(aes(x = date_var, y = dollar_var) +
   geom_line() +
   ojo_scales() +
   theme_okpi()

and ojo_scales() would automatically detect that the x variable is a date, and the y variable is a dollar amount, and it would apply scale_manual_date() and scale_manual_continuous(labels = scales::dollar), etc.

See Anthony's stuff here: https://github.com/openjusticeok/rtc-oklahoma/blob/dev/R/highchart_label_formatter.R

I don't believe we can make this a default elsewhere, so could make sense to add here, the default expand argument should be scale_*(expand = expand_scale(mult = c(0, .1)) which creates no space below the bars and the x-axis but expands the scale to 10% above the highest bar plot.
