Adding Native Token and ERC-20 Token logos on metamask

### What is this about?

**As a user** adding chains and tokens to metamask
**I want** to see logos of the tokens
**So that I** feel more secure about what tokens I have and I can easily differentiate them.

- Could we add the logos of Chiliz so that when someone adds The Chiliz Chain to metamask it has a logo for CHZ the native token.

Chain ID: 88888
Currency: CHZ
Logo: https://assets-staking.chiliz.com/images/assets/Chiliz.png

- Could we add a logo for the Community Token PEPPER so that when imported in metamask it has a nice looking logo.

The issue names no files, tests, or entry points. Start by locating the extension’s existing native-token and ERC-20 logo handling, then check how chain ID 88888 and the supplied PEPPER contract address are represented; done means both supplied logos appear in the relevant token views.
