Replace the EIP-1538 Implementation with EIP-2535, the Diamond Standard

[mudgen]

This implementation is using EIP-1538 for its upgrades. Specifically EIP-1538 is implemented in the contracts in the ProxyReceiver folder.

EIP-1538 has been abandoned and replaced by EIP-2535, the Diamond Standard.

EIP-2535, or the Diamond Standard, is an improvement over EIP-1538.

I suggest replacing the implementation of EIP-1538 in this repository with an implementation of EIP-2535. I suggest using the reference implementation of EIP-2535 to do this.

Some information about the Diamond Standard:

Here's a couple articles about EIP-2535:

One of the authors (Ronan Sandford) of ERC-1155 is currently building tooling for EIP-2535. Here is a link to his announcement: https://twitter.com/wighawag/status/1280992800545349644

I am the author of the Diamond Standard so if you have any questions or need help then let me know.
