* Update Circle develop branch

for SSD1306 display rotation support

https://github.com/probonopd/MiniDexed/discussions/412

* Implements rotation and mirroring options for SSD1306 displays (only). (#420)

Requires an update to circle (PR submitted to develop branch)

Co-authored-by: diyelectromusic <68612569+diyelectromusic@users.noreply.github.com>

* circle-stdlib e318f89

Needed to support Circle develop

* Fix for Issue 421 - circle sound drivers have moved to their own subdirectory and library.

* Updated to keep in step with updates from the original in circle-stdlib.

* git checkout circle-newlib 48bf91d
