also fine on esp32s

[DDDanny]

No Issue FYI

Thanks a lot // DANKE STEFAN! @wendlers !!! - that saved me a whole bunch of time...

***GREAT NEWS *** ESP32 (S) also works 😃
using upython 1.9.3 -> with some, real small, code extensions: that was a no brainer ... brain work has been done by Stefan.

SPI used ("HSPI") - remark: 1st, standard esp32 SPI didn't work, VSPI might work too, just try map the VSPI pins...

define HSPI pin mappings + RST aka reset module

#HSPI BUS            #NodeMCU ESP32 WROOM printed on Pin@board
ESP32_HSPI_CLOCK        = 14 #P14    (HSPICLK in ESP32 Docs)
ESP32_HSPI_SLAVE_SELECT = 15 #P15    (HSPICS0 in ESP32 Docs)
ESP32_HSPI_MISO         = 12 #P12     (HSPIQ[uery] in ESP32 Docs)
ESP32_HSPI_MOSI         = 13 #P13    (HSPID[ata] in ESP32 Docs)

ESP32_MFRC522_RST      =   3 #SD3, as plain GPIO - can be any unused GPIO

and create in reader/writer:

    elif board == 'esp32':
        #hspi                 sck,              mosi,            miso,            rst,               cs
        rdr = mfrc522.MFRC522(ESP32_HSPI_CLOCK, ESP32_HSPI_MOSI, ESP32_HSPI_MISO, ESP32_MFRC522_RST, ESP32_HSPI_SLAVE_SELECT)

further more allow esp32 same as esp8266 in mrfc522.py:
elif board == 'esp8266' or board == 'esp32':

that's all. Tags shipped with the MFRC522 are recognized fully, other china's set reads at least UID, but not the 0x08-address ("Auth error") - nevertheless for a good/bad recognition this is really fine for me.

Thanks. It's also work on Esp32 DevKit v1.
