analysis and storyline

[stuartjash]

Combining this with the changes/PR from @c7bercat. Their notes are as follows:

• changed ArgManager to Command, using this verbage is Swift best practice imo
• moved the setup code from main.swift into Command.swift::start() and Command.swift::setup(), also Swift best practice
• added an OptionSet to handle the command's options
• made adjustments in Module.swift and FileWalker.swift according to the new command option OptionSet
• the Package.resolved file was added. it details what external packages are being used in the project

Reference: https://github.com/jamf/aftermath/pull/25

• added storyline functionality
• sorting timeline and storyline
• fixed artifact gathering
• added schemes for local testing
• included package.resolved
• fixed date formatter
• moved to Command.swift
• updated timestamp formatting for what appears to be a new way macOS grabs metadata
• add dbparser for parsing databases in analysis
• added all analysis
• updated .gitignore with a traditional jamf gitignore

Again, shoutout to @c7bercat for all of the recommendations 🙏
