+fc-tmsync aur and aur-all addition
+New addition as of fc-host-tools-r16: our aur command which natively resides in
+fc-tmsh (audio mode full access read operation via ETM) has also been
+implemented in fc-tmsync for scripted usage.  Furthermore, we also implemented
+an aur-all command that issues the same sequence of aur operations as the
+firmware's built-in audio_mode_save() and emits the output on stdout in the same
+format as tiaud-decomp.  The end effect is that fc-tmsync aur-all is a much
+shorter and more direct way of obtaining exactly the same result as would
+previously be obtained by saving the current audio mode config with aus, reading
+out the resulting binary file with fc-fsio and decoding it with tiaud-decomp.
+The implementation of aur-all and the more elementary aur 12 command in
+fc-tmsync works only with firmware versions that have L1_NEW_AEC enabled -
+therefore, these commands work with FC Tourmaline but not Magnetite.
+Furthermore, our aur command in both fc-tmsh and fc-tmsync and the new fc-tmsync
+aur-all command also work against Pirelli's firmware - this alien fw implements
+ETM aur operation exactly the same as standard TCS211, and it has L1_NEW_AEC
+enabled, such that aur 12 returns the 24 byte long L1_NEW_AEC version of
+T_AUDIO_AEC_CFG structure.  The combination of this functionality in Pirelli's
+fw and our fc-tmsync addition makes it possible to read out Pirelli's highly
+tuned audio configurations in a very convenient manner, much more convenient
+than reading ABB registers with abbr and reading DSP API words with r16.
