generate code example for plotting minute-by-minute OHA for a given lake, w/ SB release as starting point

Exporting the minute-by-minute data is too much, but we can provide code to generate plots or time series data from the existing data in the data release

Start by examining the existing data in the data release and the SB release referenced in the title. Determine how a lake is selected and how the minute-by-minute OHA values are represented, then provide an R example that generates plots or time-series data without exporting the full minute-by-minute dataset.
