Name conflict with SD.h and FS.h

[awigen]

Including both FS.h and SD.h produces the following compile error:

framework-arduinoespressif8266/libraries/SD/src/SD.h:27:7: error: redefinition of 'class fs::File'
class File : public Stream {
Indexing .pioenvs/esp12e/lib/libAsyncMqttClient_ID346.a

@awigen the Arduino usage is really meant for only one file system, which here means either SPIFFS or SD.
Still, it's possible to use both, see #2281 .
Closing.
