Discover .env files in parent directory

[line-o]

Enhancement

In order to use a configuration implicitly, at the moment you have to either

• specify a .env file in each working directory
• use the --config parameter to use a central configuration file

Leveraging the find-up module a user can have a default configuration in their home directory while still being able to override this by a configuration in a descendant directory and/or providing a specific configuration file as a parameter.

This will then not only work for .env files but can be extended to also look for .xstrc.

Alternatives

There might be alternative packages that achieve the same or we could code the functionality by hand.
