Airband VOR receiver and trasmitter (#3244)

* First test * Reorder includes for consistency and fix string dereference in VorCdiIndicator * Add memory section and linker script entry for vor_rx application * Testing VOR TX * Moving VOR TX to SD * Code refactoring to align with guidelines * Add TODO comment to verify radial sign convention in vor_tx_config * Remove unnecessary set_dirty() calls in VorRxView methods * Update Course Deviation Indicator label and adjust UI element positions * Update VorTxView to run prepared image from memory map * Update build condition in nightly release workflow to include workflow_dispatch event * Reverting action changes * Adjust Course Deviation Indicator layout and refine painting logic * Refactor VorRxView UI elements for improved layout and clarity * Add calibration field and update radial calculation logic in VorRxView * Enhance VOR processing: add renormalization to phase oscillator, improve signal handling, and update configuration parameters * Implement radial smoothing and TO/FROM state handling in VorRxView; update VOR processing logic * Setting comments inline * Refactor VorCdiIndicator and VorRxView: change normalize_signed_degrees to use int32_t, update radial smoothing to use fixed point arithmetic to reduce flash usage * Update external app address end to 0xAE0B0000 * Update set_vor_tx_config to include enabled parameter for consistency * Refactor VorRx to omit decim_2 stage and update comments for clarity on VOR processing * Add RSSI, Channel, and Audio fields to VorRxView to mimic existing apps * Refactor VorRxView labels and status messages * Update VorRxView calibration field range to allow full circle input * Completing Ident transmission logic * Fixing TX gain and moving log label * Refactor VOR phase calculations and update radial offset handling for accurate bearing representation * Add low-pass filters to strip 9960 Hz subcarrier from audio output
