* Add new jammer modes Overview This PR enhances the PortaPack Jammer app by introducing eight new signal types, ported from my Flipper Zero RF Jammer app (https://github.com/RocketGod-git/flipper-zero-rf-jammer). These modes expand the app's capability to disrupt a wide range of RF communication protocols, from analog radios to modern digital systems. The implementation preserves the original app structure, resolves namespace conflicts, and ensures compatibility with the Mayhem firmware. New Modes The following modes have been added to the options_type in ui_jammer.hpp, with corresponding signal generation in proc_jammer.cpp: Noise: Generates broadband white noise to interfere with analog and digital signals (e.g., Wi-Fi, Bluetooth, key fobs). Highly effective for overwhelming receivers across a frequency range. Sine: Produces a continuous, unmodulated sine wave to jam narrowband receivers, ideal for analog FM/AM radios or telemetry systems. Square: Emits a harmonic-rich square wave, disrupting digital protocols (e.g., OOK, ASK) and systems sensitive to sharp transitions, such as remote keyless entry. Sawtooth (Experimental): Generates a sawtooth wave with a unique harmonic profile, useful for testing interference against PWM-based or niche analog systems. Triangle (Experimental): Creates a triangle wave with minimal harmonics, suitable for exploratory jamming of narrowband systems or receiver linearity testing. Chirp: Outputs a rapid frequency-sweeping chirp signal, effective against frequency-hopping and spread-spectrum systems (e.g., some Wi-Fi, Bluetooth, or military radios). Gauss: Generates Gaussian noise to mimic natural interference, targeting digital systems like GPS or data links by degrading signal-to-noise ratios. Brute (Experimental): Transmits a constant maximum-amplitude signal to saturate simple receiver front-ends, useful for brute-force jamming of basic analog devices. * Add new jammer modes Overview This PR enhances the PortaPack Jammer app by introducing eight new signal types, ported from my Flipper Zero RF Jammer app (https://github.com/RocketGod-git/flipper-zero-rf-jammer).
