Resolves #663. Updates P25 phase 2 Decoder to detect PLL lock errors for +/-90 and 180 out-of-phase. Adds support for broadcasting phase 2 channel frequency error calculations to support tuner auto-correction for frequency errors. Removes adaptive PLL bandwidth support from Phase 1 and uses a fixed PLL bandwidth for both phase 1 and phase 2 decoders. Updates the Phase 2 symbol timing gain with results from extensive testing of PLL bandwidth and symbol timing combinations. (#666)
