feat: optional custom erc20 support

[beer-1]

there is new params

• allow_custom_erc20
• alllowed_custom_erc20s

If allow_custom_erc20 is set to false, only ERC20 tokens created through the factory will be supported. If it's true, all custom ERC20 tokens are allowed by default. However, if you want to limit this to specific custom ERC20 tokens, you need to list them in allowed_custom_erc20s.
