How to update the coins file to work with the latest Komodo DeFi Framework

Instructions

Compile the latest mm2 binary following these instructions
Place the coins file in the old format in the same directory as the compiled mm2 binary
Open a terminal and navigate to the directory with both the files
Run the following command ./mm2 update_config coins coins_new

mm2 can accept any valid paths as the arguments for the source and destination files

Output similar to the following will be shown. The "Success" message indicates that the conversion was successful

03 09:13:56, mm2:169] AtomicDEX MarketMaker f48b4ad DT 2020-07-28T17:25:18+07:00
Success

You will find a new file named coins_new in the same directory with the new format expected by Komodo DeFi Framework
Rename the file named coins to coins_old and then coins_new to coins
mm2 will use the coins file in the new format the next time it is launched
