Better handling for MM2.json config not found error

[damascene]

When I launch the bot without having a config file MM2.json in pytomicDEX_makerbot/config/ I get the following error:

FileNotFoundError: Komodefi SDK config not found at /home/user/pytomicDEX_makerbot/config/MM2.json!

Traceback

coins file not found, downloading...

FileNotFoundError: Komodefi SDK config not found at /home/user/pytomicDEX_makerbot/config/MM2.json!

I think printing an error and suggestion to get the file would be better.

This looks like an unfinished refactoring or outdated code, because makerbot should generate the MM2.json. For me the following patch fixes all the errors appearing on startup:
