Show HN: Pydockenv v0.6.0 is out! Easier installation & increased compatibility

`pydockenv` has been completely ported to `golang`. This makes the installation much easier since it doesn't have any Python dependency, hence no conflicts during installation outside of a virtual environment.

Currently it has to be installed with `pip`, so Python is required to install it. Once different ways for installing it (package mangers, package in GH, etc.) are provided, Python itself won't be a dependency (you'll be able to run Python environments without having Python installed).

Having `pydockenv` written in non-Python makes also the development itself easier since no meta usage of `pydockenv` is needed.
