[IMP] hardware: Minor Rewiring and alignment changes * Improve wiring around FT232R * Move passives around to allow more room for ground plane * Update Net Names so they make sense

[IMP] firmware: Update Application * Rename io_mappings to mappings to match bootloader * Add CLI files * Update handler to use BC127 auto-connect rather than manually connecting

[IMP] hardware: BlueBus Rev A v4 * Add quad tri-state buffer to make system UART selectable between the MCU and BT module * Replace MCP2221A with FT232RQ in order to be able to use even parity UART for BT Module firmware updates

[IMP] hardware: Clean up traces * Clean up trace runs so we use less VIAs * Ensure that VIAs are not mid-trace on signal lines

[IMP] hardware: MIC IN Fixes

[IMP] hardware: PCM5102AQ1 fixes * Remove +3.3 from LDOO caps * Wire XSMT & FMT back to +3.3 * Rewire feedback pin of +5v switching regulator

[IMP] LICENSE/README * Disallow commercial use of board in license * Update README

[IMP] firmware: BlueBus Rev A Updates * Update pin mappings to match new board layout

[IMP] hardware: BlueBus Rev A * Improve Silkscreen * Rewire a couple of nets to reduce via count * Move passives into better alignment
