* feat(yay): add boolean flags
This feature now allows users to specify --<option>=<bool value> instead
of using --<option> and --no<option>. Specifying nothing results in the
boolean value being true. The flags prefixed with `no` are deprecated.
* chore(args): Print warning when using deprecated flags
* chore(yay): Update man page for deprecated options and add examples of
boolean flags being used
