card fixes and adjustments (#116)

* fix name comparing when creating save files (creating set when set_sav exists)
* add functions found in gcmm to retrieve the amount of free blocks & the memory card serial numbers
* Add GetStatusEx & SetStatusEx wrappers
* expose raw read/write functions (so MC tools can use them)
