Improve error handling and logging in parser

[ferdlestier]

Implements improved error handling and logging in parser.py and updates documentation in README.md.

• Error Handling and Logging in parser.py:

  • Imports the logging module and configures logging with a basic setup to write logs to parser.log.
  • Wraps the entire data parsing and analysis code block in a try-except structure to catch and log exceptions.
  • Adds logging statements at key points in the script to log information about the script's execution flow, such as successful loading of the CSV file, calculation of top daily growth and loss, and tracking of financial exposure and return on invested capital.

• Documentation Updates in README.md:

  • Adds a new section on error handling and logging practices, explaining the importance of these improvements.
  • Provides guidelines on how to view and interpret the logs generated by parser.py, enhancing the user's ability to monitor and debug the script's execution.
