Fixes and refactoring (#59)

* Input url list: Fix bad Windows behavior

* Minor output fix

* Fix all download issues
  - downloads are synchronous again
  - fix progress bar (fix #39)
  - nuke fluent and switch to a bug-free ffmpeg module (fessonia)

* Move destreamer process events to a new file, we may add more in the future, lets give them their own space

* Destreamer: Release packages and builder script

ETA when? :P

* Clean up

* Implement yargs checks and add --videoUrlsFile option

* Refactor error handling
  - Human readable
  - No magic numbers

* Handle mkdir error
  - remove reduntant message

* gitignore: don't add hidden files

* Implement --outputDirectories

This gives us more flexibility on where to save videos

..especially if your videos have all the same name <.<

* Rename utils -> Utils

* Fix tests

don't import yargs on files other than main

* Create scripts directory

* Update make_release path

* Fix typo

* Create CONTRIBUTING.md
