This PR does not resolve any outstanding issues.

• Attempted to fix "missing data" flag issues
  • There are issues inside of the large_anomaly_flag function and generate_flag_report function that I am not positive are resolved. There many combinations of flags that have "missing data" in them and I am not sure that I got all of them.
• Moved functions from 01-organize_raw_data.Rmd to their own folders.
  • verification_functions
  • plotting_functions
  • flagging_functions
  • data_munging_functions
• Created flagging_descriptions folder for the flag markdowns.
  • Created standard_deviation_flag.Rmd and pushed the .html as well.
• Moved the percent_flagged script from scratch/misc. into the qaqc folder

I'm pulling without reviewing, as I plan to make substantial changes that I will be submitting as a pull request to you @juandlt-csu. Stay tuned for that this evening!
