Matthew Huxtable 8072e66d46 Add delete command
The delete (short option "d") will delete the YAML subtree at the
provided path in the specified file (or STDIN), if it the node exists.

More complex support is currently omitted, for example:

  - specify nodes to delete using an external script
  - deleting common elements from all elements of an array
