OpenBrush Chain Extension library

The library provides tools and primitives to simplify the development of chain extensions for ink! and for the substrate.

The library provides macros that allow implementing the same trait on ink! and substrate. Macros generate all logic related to encoding and decoding arguments, calculation of functions id and extension id, matching function ids, and returning errors. On the substrate side, you need to implement the trait and write the logic of each method. The ink! side will already be prepared to pass all data to you.

TODO:

• Add unit tests
• Add examples and documentation
• Setup CI
• Add support of the obce::weight attributes for method to simplify benchmarking of the chain extension.
• Maybe ore features based on the use cases=)
