Add additional logging statements.

[chloehumphrey]

We need to add some more logging statements to the program.

Instead of importing pino to every file, I've created a logger.ts config file. This is setup to output to a file specified in the .env file.

Setting the program up with logging:

1. Create 'logs' folder in the root directory Add these lines to your '.env' file:
2. LOG_LEVEL = 1
3. LOG_FILE = ./logs/app.log Run normally, you'll see the file fill up

LOG_LEVELs: 0 : silent 1: info 2: debug 3: error

• [x] Add logging to the metric classes
• [x] Make sure we're adding "debug" logging statements in addition to "info"
