Set up SEATRACK DB credentials for this project
set_credentials_renviron.RdThis function will store credentials to access the seatrack database in a .Renviron file, meaning they can be automatically be used when connecting to the seatrack database. If the project is git controlled, .Renviron will be added to .gitignore to avoid credentials being leaked. This function should only have to be called once, when setting up a new project. While the option is there to directly put your credentials in as arguments, do NOT put it in your script with the password in plain text, as this defeats the purpose.
