feat: add Velocity Units (pimlie#8)

* feat: added velocity unit type


fix: Added correct unit systems to velocity units

* added .idea to gitignore

* fix: adjusted spelling, added aliases

Added aliases for Mile based Velocity Units as per code review.

* fix: Adjust test to account for added unit types
