Fix stuttering issues on detailed models

- Optimize TFT code for state handling (pause, runout, ...) - Remove multiple state booleans in favour of a single integer - Remove obsolete filament runout code - Increase jerk/accel - Decrease TX buffer size - Revert minimum segment time to factory default

-Feel free to discuss issues and work with me further optimizing this firmware!
-
-I am running this version on an i3 Mega Ultrabase V3 (for distinction of the different versions, check [this Thingiverse thread](https://www.thingiverse.com/groups/anycubic-i3-mega/forums/general/topic:27064)).
-Basically, this should work on every Ultrabase version that has two Z-axis endstops.
-
-The new Mega-S should work too, but you will need to enter those two commands to make the new extruder work:
-```
-M92 E384
-M500
-```
-Afterwards, calibration is highly recommended as per the instructions on the [Wiki](https://github.com/davidramiro/Marlin-AI3M/wiki/Extruder-Calibration/).
-
-Note: This is just a firmware, not magic. A big part of print quality still depends on your slicer settings and mechanical condition of your machine.
+Looking for a **BLtouch firmware**? Head [this way](https://github.com/MNieddu91/Marlin-AI3M-BLTouch)! Mounting and configuration instructions are included.

 #### Make sure to take a look at the [Wiki](https://github.com/davidramiro/Marlin-AI3M/wiki/), especially the [FAQ](https://github.com/davidramiro/Marlin-AI3M/wiki/Frequently-Asked-Questions).

-## Known issues:
-
- **Cura users: Please turn off jerk and acceleration control in your print settings (not visible by default, select advanced visibility to unlock them). Cura's high default jerk and acceleration might cause shifted layers if you use TMC2208.**
- Estimated print times from your slicer might be slightly off.
- Special characters on any file or folders name on the SD card will cause the file menu to freeze. Simply replace or remove every special character (Chinese, Arabic, Russian, accents, German & Scandinavian umlauts, ...) from the name. Symbols like dashes or underscores are no problem.
-**Important note: On the SD card that comes with the printer there is a folder with Chinese characters in it by default. Please rename or remove it.**
- Cancelling prints via display is buggy sometimes, simply reboot the printer when the menu shows an error. Protip: Switch to OctoPrint.

+While the i3 Mega is a great printer for its price and produces fantastic results in stock, there are some improvements and additional features that this firmware provides:

 - Many people have issues getting the Ultrabase leveled perfectly, using Manual Mesh Bed Leveling the printer generates a mesh of the flatness of the bed and compensates for it on the Z-axis for perfect prints without having to level with the screws.
 - Much more efficient bed heating by using PID control. This uses less power and holds the temperature at a steady level. Highly recommended for printing ABS.

 - Even better print quality by adding Linear Advance, S-Curve Acceleration and some tweaks on jerk and acceleration.
 - Thermal runaway protection: Reducing fire risk by detecting a faulty or misaligned thermistor.
 - Very loud stock stepper motor drivers, easily replaced by Watterott or FYSETC TMC2208. To do that, you'd usually have to flip the connectors on the board, this is not necessary using this firmware.

+- Filament change feature enabled: Switch colors/material mid print (instructions below) and control it via display.
+- The filament runout, pause and stop functionality have been overhauled and improved: The hotend now parks and retracts (on pause or stop) and purges automatically (on resume).
+- Added `M888` cooldown routine for the Anycubic Ultrabase (EXPERIMENTAL): This is meant to be placed at the end Gcode of your slicer. It hovers over the print bed and does circular movements while running the fan. Works best with custom fan ducts.
+  - Optional parameters:
+  - `T<temperature>`:   Target bed temperature (min 15°C), 30°C if not specified (do not set this under room temperature)
+  - `S<fan speed>`:   Fan speed between 0 and 255, full speed if not specified
+  - e.g. `M888 S191 T25`: run the fan at 75% until the bed has cooled down to 25°C
