Unbinding `ff_currentcluster` and `f_pos`: 1. Added `ff_pos` in `struct fat_file_s`. 2. Added function `fat_zero_cluster` for doing zeroing for gap between EOF and new position beyond EOF. 3. Added function `fat_get_sectors` for getting the sector where `f_pos` is located, allocting new cluster when `f_pos` is beyond EOF. 4. Modify function `fat_read`, and `fat_write` with above functions. 5. Remove redundant logics in `fat_seek` since now new cluster is allocated when writing instead of seeking.
