V30I: Add option to enable/disable N64 CRC32 checking

Browse Source 
In Cart_Reader.ino line 71 change "boolean n64crc = 1" to "boolean n64crc = 0" to disable the CRC32 check when dumping roms. This is useful if you rather calculate the checksums on your much faster computer. Calculating the CRC32 is enabled by default now and can take quite some time.
