0.2.1

Changes in 0.2.1

• Make sure to only work with regular files

  This solves problems that arised when there were symlinks in the search
  path, or when a file was scanned in a previous run and afterwards there
  is a directory with the same path and name. This could have resulted in
  "unreachable code" errors or random panics.

• Performance boost due to skipping needless object creations

• Update dependencies

• Update base16ct to 1.0.0
