v0.4.0

This is a major rehaul of crate. Older versions are going into deprecation soon, as they are desperately obsolete at this point.

Features:

• no-std compatibility
• External memory support to dynamically access metadata and call without full copy into memory space
• Shortened metadata support
• More sane short specs structure
• Properly parse unchecked extrinsics

Bug fixes:

• Multiple minor fixes in rarely used extrinsic structure

New Contributors

• @dependabot made their first contribution in #20
