Description

The PR adds a possibility to mirror previously deployed ERC-20 contracts on the main Aurora contract. The transaction mirror_erc20_token is allowed in the Silo mode only.

mirror_erc20_token accepts parameters serialised with borsh. get(set)_erc20_metadata accepts parameters serialised with JSON.

Performance / NEAR gas cost considerations

There are no changes in the performance/gas consumption.

Testing

The corresponding test has been added.
