Coinbase websocket client on Golang

Task

1. Connect to the Coinbase cryptocurrency exchange via WebSocket
2. Subscribe to prices for three instruments: ETH-BTC, BTC-USD, BTC-EUR (data will come in through the WebSocket as they appear on the exchange)
3. Create a "ticks" table in MySql with the following fields:
   • timestamp (int64) - price time
   • symbol (string) - instrument name
   • bid (float64) - selling price
   • ask (float64) - buying price
4. Connect to MySql and write data received through WebSocket to the ticks table
5. Write data from the three instruments (ETH-BTC, BTC-USD, BTC-EUR) to the database in three threads (each instrument has its own write thread)
6. Publish the project repository on Github
7. Use good development practices to enable further application functionality expansion
