This PR introduces a CommandIo type that provides a centralized implementation of input and output file/stream setup. Individual commands are no longer responsible for detecting I/O errors, configuring decompression, or setting up termcolor's output streams.
It also:
Makes dump a deprecated alias for the command's new name: cat.
Factors out the transcription logic shared by both head and cat.
Adds a CommandInput type that remembers the name of the input stream and what type of compression it detected.
Adds a CommandOutput type that statically dispatches over File/StdOut and supports termcolor.
