Make token decimals easier to configure

[artursapek]

Right now, this config is inadequate because it's lacking tokensConfig.ZOOMER.decimals.Solana being defined as 8. This causes Solana balance to display incorrectly.

That shouldn't be required. Having it defined under foreignAssets should be adequate.

{
    networks: ["ethereum", "solana"],
    env: "mainnet",
    tokens: ["ZOOMER"],
    tokensConfig: {
      ZOOMER: {
        key: "ZOOMER",
        symbol: "ZOOMER",
        nativeChain: "ethereum",
        tokenId: {
          chain: "ethereum",
          address: "0x0D505C03d30e65f6e9b4Ef88855a47a89e4b7676",
        },
        coinGeckoId: "zoomer",
        icon: "https://assets.coingecko.com/coins/images/30894/large/zoooooooooomer.jpg?1696529740",
        color: "#FEFC52",
        decimals: {
          default: 18,
        },
        foreignAssets: {
          solana: {
            address: "nBZEcHSG771mRbi4y2sSgKjfDUH8jsM2Eo5fNcASLeU",
            decimals: 8,
          },
        },
      },
    },
    rpcs: {
      solana: "https://rpc.ankr.com/solana",
    },
  }

I resolved this problem by change decimals config, ex:

{
      decimals: {
        default: 18,
        Solana: 8,
      },
}
