Add basic sample rate conversion to the CXD56 Spresense audio driver using libsamplerate. Currently conversion is only done during playback and all output is fixed at 48 kHz. Issues: - 16 kHz SRC has glitches (unless data dump is enabled) - 44.1 kHz SRC gets stuck Signed-off-by: Alin Jerpelea <alin.jerpelea@sony.com>
