Release version 0.9.0

* `convert` argument for `EUci.get`. It provides a way to convert values
  to any type with custom function.

* `list` argument for `EUci.get` is now required to be set to `True` for
  lists otherwise only first value is returned. This is removal of
  auto-detection of lists. The get of list has to be now always
  explictly stated.
* `dtype` argument for `EUci.get` can now be any type that can be
  initialized with string as a single argument (such as `int("42")`.
* `default` argument for `EUci.get` now uses object instance `NoDefault`
  to detect that there is no default instead of presence of keyword

* obsolete "get" methods in `EUci`
