Adding optional argument parsing to the tool

[ishaansehgal99]

Simple argument command line parsing.

We need this because we have three potential arguments that can be passed into the program

1. -d destination directory for storing hibernation setup tool exe, and hibernation setup tool service
2. -w when, when running hooks -w used to specify "pre" or "post" hook
3. -a action, specifies we are running the "hibernate" action, in future if we want action like "suspend" or "hybrid" this parameter can be changed

Currently command line parsing is done by arbitrarily taking the next two arguments in argv, assuming their order. Now with three arguments we use more specific command line parsing, to ensure parameters are passed and get executed on as expected.

Looks good to me. Thanks!
