François d6f843e081 script: add flash_erase/write/verify, flash_read to file (Phase 4) ...

Completes the flash command set over the BSCAN proxy:
 - flash_erase <dev> <addr> <len>  : erase covering sectors (destructive)
 - flash_write <dev> <addr> <file> : program from a file (no auto-erase)
 - flash_verify <dev> <addr> <file>: compare flash against a file
 - flash_read gains an optional [file] arg for a raw binary dump (backup)

Validated on the KCU105 with a save -> erase -> write-random -> verify
-> erase -> restore round-trip (region left untouched). Apparent write
throughput ~100 KB/s once the proxy is loaded.
