Betaflight 3.5.2 - F3 Board Performance Edition

These are F3 board flight performance focused releases of Betaflight 3.5.2a. What at is the ".2a" part you ask? Whelp, some of the commits between 3.5.2 leading up to the 3.5.3 release are included. If you are looking for F4 or F7 targets, see https://github.com/betaflight/betaflight/releases

These targets add the features: Throttle Boost, iTerm Relax, RC Smoothing Filter, Gyro Lowpass2 filtering, Extended CMS menus, RTC time, and ESC Sensor Info. support to F3 flight controllers. To make flash space available the PWM, SUMD (Graupner Hott), SUMH (Graupner Legacy) and XBUS (JR) receiver protocols were removed along with Servo support and some other internal functions.

Stock features removed varies per F1 and F3 boards. a.k.a not all F3 boards have all the above features removed on the stock HEX builds. It really depends on their ROM space and other features of the board; like whether they have a baro or not, etc... OmnibusF3, BetaflightF3 and some of the SPracingF3 targets are the hardest to get things to fit. See commits for what is included or not.
