This reads raw NFC tag pages by calling send_nfctag_cmd() with cmd 0x3A("FAST_READ"). The output-data is stored on stack, which is copied to the specified output-buffer afterwards using the actual_output_size. An error is returned if actual_output_size is larger than outputsize.

outputsize 0x800 is used when it's >=0x800.
