Bump version to 0.0.5 and removed autofocuser ValueError on bad conditions

[ppp-one]

Removed autofocus ValueErrors on bad conditions. Tests in Astra succeeded (see code here), however, astrafocus pytests failed to run because of issues with my modified config.yaml (it didn't seem to like Astra generated fits files).
