There is no difference between 4k erase and sector erase. But sector erase would previously do `.block_erase` which would not erase a sector (4k) but a whole block (64k). Fortunately all boards declare `SPI_NOR_F_SECT_4K` and all file systems don't try to erase anything smaller, so this was never triggered. Add an `assert(0)` to crash instead of corrupting data.
