As requested in #11 and #13, added a new CLI option (--file) to read from a file instead of just standard input.
Personally, I would prefer it as a positional argument but i think it will conflict with the current interface.
In order to do it in a more "elegant" way, I have refactored the argument parsing to use python standard library's argparse module.
Then, added the new option which defaults to read from stdin and accepts a filename as value (and "-" as another way to read from stdin). Error handling for non-existing input file should probably be added.
Migrating to argparse causes an error for previously valid argument ordering. E.g., the following call is no longer valid:
cat <FILE> | shyaml get-value -y <KEY>
the valid call would be (notice the y-flag position):
