Reverted 'mfr_id' to 'manufacturer_id'
Moved devices table definition to flashmem.h
Single global variable 'spi_flash_pages64k'
The local structure holding the actual device data is used in firmware.c only
difference in code:
```
text data bss dec hex filename

```
* introduced a new communication command CMD_FLASHMEM_PAGES64K to get the number of 64k pages
* "the last page" is a special, holding the dicts and some other stuff, relocated to there
* raised timeout when wiping a mem page (W25Q16 looks a bit slower than W25X20BV)
* loop all pages in Flash_WipeMemory()
Improved algorithm for hf iclass legrec by taking in account the hash0 limitations for the ending bits distributions of each key bite, thus reducing the key entropy and number of required tries from 2^24 to almost 2^19
