Subject: Count occurrences of flags (was "Add .count type for flags") (#96)

Breaking change: parseEx now counts the number of occurrences of flag
parameters (those with takes_value == .none) and returns the count as a
u8.  Users of the library will need to change

    if (arg_result.my_flag)

to

    if (arg_result.my_flag != 0)
