U256

This module provides a U256 type that represents an unsigned 256-bit integer. It uses the construct_uint macro from the ff_uint. Additionally, the module provides a conversion implementation from sp_core::U256 to U256, and vice versa.

The module defines a from_const_str method that constructs a U256 from a string of decimal digits. The string is passed as a byte slice, and the method will panic if any byte in the slice is not a digit.
