ERC-138128: Custom function selector and calldata encoding scheme declaration standard

• A contract SHOULD use ERC-165 standard to declare its support for ERC-138128 standard.
• A contract supporting ERC-138128 MUST have these two view functions: customSelectors() and customEncodings().

customSelectors()

This function is used to declare alternative function selectors for any number of standard function signatures. This function MUST have the following interface.

// The Setup
// ---------
// Alice, Bob, and Mallory have a tea party
// Alice decided to give everyone tokens!
// Alice sets up a Proxy contract and a Token contract
// The tokens are shared between the three friends
// initialSupply is 30000000000000
// But are they truly friends? Or ex-friends?
