Compiler warnings for deprecated functions

[alba-ado]

While using the newest espressif32 platform in the PlatformIO, the library gives a compiler warning. The warning is as follows;

Actually similar issue I had reported to espressif and this deprecation warning should not happen in later releases. At least, they have linked to a commit, which removes the deprecation warning.

Ok. Thank you.

Closing this issue.
