Add some flashcarts dumping support

Browse Source 
Add support for :
- "16M / 32M Pocket Flash Card" : old flashcarts, respectively in black, and transparent purple cases. Since their flash chips are returning 0x204C value (4Mbits), you will need to manually select the wanted ROM size before dumping them.
- "NeoGeo USB Flash Masta 2 in 1" : contains 2x 16Mbits Fujitsu chips, now detected fine.
