esp32dmaspi 2.0.0 won't compile on linux with arduino 1.8.19

[emard]

Arduino 1.8.19 downloaded and installed, with manage libraries installed ESP32DMASPI v0.2.0 and loaded example "master_simple"

it compiles with v0.1.2 but with v0.2.0 compile fails with some error:

There are already tickets open for this. Please read #13 and #14

@emard Hi, v0.2.0 requires ESP32 version >= 2.0.0 for Arduino IDE, and not supported on PlatformIO now. Added supported version matrix to README
