Support for Nicla Voice Board

[mighty-sparrow]

This is not the same as #702 or #704.

Need support for the Nicla Voice board, ensuring it's possible to leverage the libraries intended for use specifically with that board (...and are already included in the framework deployed with pio).

For a sanity check, I'd like to deploy the Record_and_Stream example included with the NDP library. For PlatformIO, it's located at .platformio/packages/framework-arduino-mbed/libraries/NDP/examples/Record_and_Stream.

Here's a shortcut to the product page tech specs and docs.

Of course, if there's some other way to accomplish this I'm all too happy trying that route first.

Many thanks in advance!
