SPI Fails for new ESP-IDF

Hi,

First, thanks for this amazing port! It saved me a lot of headaches. For the past year, I have been using it over ESP-IDF v4.3 and v4.4.2 but I had to do some minor changes to make it run.

First, the includes for epdif.h and other alike had to be changed to epdif.cpp and similar. Likewise, I had to remove the definiton of SPI_HOST because it is now defined under spi_types.h

It would be my privilege to contribute to the project. I have already fixed them on my local branch but I lack the permissions to push it to the repo and then open a pull request.

I also plan to introduce version checking to make it more adaptable.

Let me know if you are interested!

Wrong SPI host

Hi there, I ran into a fault when I need to init SPI for a second time after adding some sleep/wake features

• The issue is in line 72 of epdif.cpp
  spi_bus_free(VSPI_HOST);

• I believe that this should be
  spi_bus_free(HSPI_HOST);
  since the HSPI host was used during bus initialization in line 100
  ret=spi_bus_initialize(HSPI_HOST, &buscfg, 0);
