Get first tries to read the passed files and then overrides the .env file parameters with the environment variables in memory.

GetEnv returns a map of OS environment variables.

Parse uses my simple-configo package that allows to easily parse environment maps and do proper value conversions as well as setting your configuration's struct fields after parsing the values.

Read reads .env files that are passed to this function and returns a map of key values .env files have the same syntax as environment variables KEY=VALUE.
