Edge and CSV parser

[stuartjash]

• added support for Edge browser (pretty much identical to Chrome)
• fixed typo in browsers.txt file
• instead of using computer name for aftermath directory name, using serial number instead. This is much more consistent. if serial number comes back as null, use the device name
• removed timestamp from file name to remove clutter and added a 'started collection' log line in the aftermath.log
• Wrote our own csv parser as the SwiftCSV package was throwing errors and they were unable to be handled gracefully. This change required rewrites to much of the analysis section. This should address Issue quotation(message: "Can\'t have non-quote here: F") #38
• added macOS 11 compatibility for collection only. Analysis still requires macOS 12 or greater. Per issue Does not run on macOS 11 #41
• updated program entry to exit if not root
• added shields to readme for readability
