+// 23.12.2021: V1.1  added block-parameter to function "read mifare data"
+// 30.12.2021: V1.2  added function: mif_clearDataBuffer(), mif_isBlockAvailable(uint8_t blkNr) and mif_getAvailableDataBlocks()
+// 1.1.2022: V1.3    Mifare extended. ( background: read 16 x 48byte from card to DC, read 12 x 64byte from DC to CA)
+//                   new:  read full card with 768bytes from HWapi without block borders
+//                   added: mif_getNrOfAvailableDataBytes     mif_getCardData768byteDec(uint8_t *buf, uint16_t bufferSize)
