Added
- New boolean parameter `decode` to class `FixedStringField`. It defaults to `False` meaning the internal value is
considered as bytes, if `True`, it will be considered as a string.
- Support for python 3.10.
Changed
- Replace `is_bytes` parameter on class VariableStringField to `decode`. The meaning now changes. If `decode` is `False`
which is the default case, the internal value is considered as bytes, if `True`, it is considered as a string. - (4)
