When using env files with lines > 64k parsing would fail due to the Scanner's default maxToken size.
It seems that using ReadLine is the optimal manner to resolve this
Particularly as I don't see a good way to expose the max token size as part of godotenv.
But I am new to GoLang so maybe I am missing something...
