feature: enabled multi-line parsing of env files

[VijoPlays]

With this PR it should be possible to read an .env variable from a file with multiple lines.

One minor issue for the tests:

I can't seem to get the EnvReader to find the new env file I created for the tests. Would be nice if you could take a look and merge this in the next couple of days.

This closes #29

@VijoPlays I have to revert this PR as the multi line reader doesnt work as expected and the test for it fails

@bolorundurowb yes, that's the issue I mentioned in the PR:

The reader itself behaves correctly, it's probably just a pathing error or something in the tests.
