v2.0.0

Major Changes

• #41 295d847 Thanks @s0! - Make repo argument required,
  and remove the repository argument which was deprecated
  and previously could be used in its place.

• #40 4117e39 Thanks @s0! - Refactor & clean up options for multiple functions

  • For commitFilesFromDirectory:
    • Rename workingDirectory to cwd for consistency across repos,
      and utils like exec
    • Make cwd a required argument
  • For commitChangesFromRepo:
    • Merge repoDirectory and addFromDirectory into a single required argument
      cwd. This folder will now both be used to filter which files are added,
      and to find the root of the repository.
    • Introduce recursivelyFindRoot option (default: true),
      to optionally search for the root of the repository,
      by checking for existence of .git directory in parent directories,
      starting from cwd.

  This effectively removes all usage of process.cwd() within the package,
  instead requiring all usage to be very explicit with specifying paths.
