Proxlist

- Adds `country` parameter to filter proxies by their two digit ISO country codes
- Adds `google_verified` parameter to filter proxies by if they are google verified or not
- Adds altered timeout logic (shorter timeouts for larger proxy pools to get to a working proxy faster, longer timeouts when the proxy pool is smaller to offset the difference and get a working proxy back to you)

- Have a stricter validation timeout of 1 second instead of 3 seconds to improve performance and accuracy based on your connection and location

- Removes proxy list from repo entirely
- Retrieves an updated proxy list each time you request a proxy
- Tests that the proxy works prior to returning it to you

- Overhauls the proxy list with different proxies (tested more thoroughly) as well as moves the list from a hardcoded constant to a text file

- Initial release allowing you to retrieve a random proxy or a list of proxies from a small initial list
