First pass rewrite of flashmem driver for optimization. Lot of changes here. Provides PoC of saving and recalling a tag in Standalone mode. Added some printing passthrough to client to azccomodate for vt100 eye-candyness. FastREAD mode implemented for flashmem, testable from client. Beta but functionnal. Reading the whole flash with 1Kb to 32kb buffers was ~730ms, now 380ms Max (even at 24Mhz spi baudrate)
