[FL-520] Filesystem Api and App (#280)

* update fatfs integer types * fix sector size to 512 * fix sector size calculation * common fs api * fs api realization (sd card + fat fs) * better sector size definition * more api realization fns * add error description api, add common api * fix api flag naming, run app * add fs_info call * disable fatfs strfuncs, enable fatfs chmod * rework filesystem app * sd detect cycle, sd menu, sd eject feature * fix sd detect cycle * sd card format routine * ui improvements, sd info routine * properly unmount card * separate mode flags * add api folder, move app, rename app * fix api naming * update st-card-test to use api * update path to app * fixed potential problem of using sizeof union * updated api documentation, new time/date fns * update codeowners * changed app requirements * changed app order * sd insert/remove log
