Some errors in the compiling

[murarduino]

I had some errors compiling

1. ESP32_MAS.cpp Line 42:
   ptr += is;
   The word types on both sides of the expression are different. Should it be rewritten as follows:
   *(unsigned int*)ptr += is;？

2. ESP32_MAS.cpp line 217: i2s_write_bytes() is obsolete. This needs to be replaced by the i2s_write() function. But the size_t *bytes_written parameter is newly added to i2s_write, so how will this parameter be set?

in addition, I don't see any enforce aiff files throughout that code. I would like to ask, if I use 8bits/22MHz Wav file can play?
