Minor bug fixes and improvements

- Update `README.md` file with minor changes
- Added `max_results` parameter to config for persistence
- Added `csv2`, `tabulate`, and `indicators` as included dependencies
- Added downloading progress bar that *sometimes* work
-Added HTTP request header handling with curl
- Added more options to some commands
- Moved `http` functions into `context` class

TODO: Fix optional parameters not working correctly
NOTE: Github does not always return `Content-length` HTTP response header
