[IMP] hardware: Revision D.1 * Remove errant layers

[IMP] firmware: Application 1.0.9.15 * Add Volume & Mic Gain to BMBT UI * Fix debug ignition setting * Initialize the PCM5122 on boot * Fix the MID UI not re-drawing the menu when the radio overwrites it

[IMP] project: Update gitignore

[IMP] hardware: Remove eagle.epf file

[IMP] hardware: Rev D.2 * Remove debug pads * Reroute Audio pairs from DAC * Additional Ground VIAs

[IMP] firmware: Application 1.0.9.14 * R/T button on the steering wheel inconsistently pause/plays. I fixed this by instead using the talking head button for Pause / Play (only when not on a call). * The CD Changer status is now sent out any time the BlueBus sees the "ignition status" message. This is to hopefully prevent certain buggy Navigation radios from "forgetting" that it should be in CD Changer mode when you start the car. * The telephone button on the BoardMonitor now works like the "talking head" button on the steering wheel. Long pressing it will also activate Siri/Google Assistant. * The "3" button on the Business CD can now be used like the "talking head" button. Pressing it twice within a half second will activate Siri/Google Assistant. * MID Support is now pretty much done * You can now set the BlueBus "name" on the command line using the "BT NAME " command. * You can now set a BT Pairing Pin on the command line using the "BT PIN <4 digit pin>" command. * Do not display missing metadata as blank * Power off after timeout plus one seconds to hopefully prevent issues failing to sleep
