plot_input: Plot water balance inputs for one or more lakes
In cvoter/isoH2Obudget: Lake Water Budget Using Stable Isotopes

This function creates a plot object that showcases a given input over time for each lake of interest.

plot_input(
  df = NULL,
  ydata,
  ylabel,
  yscales = scales::scientific,
  geom_type = "col",
  title = "",
  facet_scales = "fixed",
  lakes = c("Pleasant", "Long", "Plainfield"),
  inputs_only = TRUE,
  date_intervals = "6 months",
  date_formats = "%b '%y",
  text_size = 10
)

`df`	optional data frame passed to function containing columns "date", ydata, and "lake". Avoids need to run `runall_csls_inputs` or `runall_csls_budget` as part of this function.
`ydata`	colname of input data to display, e.g., "dV_m3" or "d18O_evap"
`ylabel`	string to display for y-axis title, e.g., "expression(Change~Lake~Volume~(m^3))" or "expression(delta^18*'O')"
`yscales`	type of scaling for y-axis, defaults to scales::scientific. Other options include scales::number for decimal format, scales::percent for percentages, etc.
`geom_type`	defaults to "col" to dispay as bar plot. Set to "point" to instead display as points, or "line" for lines.
`title`	string to display for title, defaults to "".
`facet_scales`	type of scaling of axis for facets, defaults to "fixed". Can also be "free_y", "free_x", or "free".
`lakes`	names of lakes to plot, defaults to include all: "c("Pleasant", "Long", "Plainfield")"
`inputs_only`	logical defaults to TRUE to trigger `runall_csls_inputs`. Set to FALSE to trigger `runall_csls_budget` instead (i.e., to obtain groundwater inflow or outflow values).
`date_intervals`	string with desired break interval for dates, defaults to "6 months".
`date_formats`	string with desired formatting for date labels, defaults to "%b '%y" for "Oct '19"-type formatting.
`text_size`	size of text, defaults to 10 pt.
