v1.0.0a2 alpha release

⚠️ This alpha release is not backwards compatible with earlier releases

This version is a pre-release and compatible with upcoming MetadataV14 and PortableRegistry.

It has the following breaking changes:

• All properties of Struct SCALE-objects in existing type-registries are now converted from CamelCase to snake_case, to be compatible with generated PortableRegistry structs
• scale_obj.value always contains a serialised version in Python primitives
• scale_obj.serialize() will contain a human readable format
• scale_obj.value_object contains the full nested SCALE objects if applicable. A short-hand of scale_obj.value_object[‘accounts’].value_object[0].ss58_address is scale_obj[‘accounts’][0].ss58_address. If the scale_obj is a Vec this will also act as an iterable.
• Reformatting of value attributes of many ScaleType classes; in particular Extrinsic and Event
• Metadata decoding has been completely refactored and should use MetadataVersioned in stead of removed MetadataDecoder
• Output format of metadata functions changed
• All ScaleType classes moved to types sub-package; block sub-package is removed
