added LoadFS from embed files

This adds the functionality of loading env files using embed.FS
Issue #138

@Enrico724 This is generally working for me, but it seems to be missing a method: OverloadFS.

@mickeyreiss @joho I've just implemented OverloadFS.

@Enrico724 Awesome, thank you. I will pull this commit and post again if we encounter any issues.

This is working well for a large production application. Is there a path forward for merging this PR?

@mickeyreiss yes, there is

@Enrico724 you should use io/fs.FS instead of embed.FS. io/fs.FS can take other FS (e.g. afero) implementations too, whereas embed.FS can't.
