Why:
* Want to be able to selectively apply filepath expansion to:
1. Only options in a stowrc file.
2. Only options that take a file path.
* Because of need 1, any expansion must be performed on stowrc options
before merging with cli options.
* Because of need 2, stowrc options need to be parsed before expansion
in order to know which options need expanding.
This change addresses the need by:
* Create parse_options()
* Implements option parsing logic previously in process_options()
* Takes an array as parameter instead of assuming ARGV
* Edit process_options() to still work as expected.
* Only change was to call parse_options() instead of directly
parsing ARGV
* By factoring out the option parsing code, we can reuse the existing
parsing code for stowrc options.
* Allows expansion of only the option itself, i.e expansion on
"$HOME/target" rather than "--target=$HOME/target"
* Allows easy determination of which options need expansion.
