joystick control: optimize turn behavior

[Jonny999999]

issue

currently making a hard turn using joystick in any quadrant seems weird / is almost not possible
thus changing to full turn mode (wheels in opposite direction) is usually necessary.

• at low angle (Y almost at 0) radius is not 1? noticed outer wheel slowing down compared to at 45Deg max radius

ideas

• set inner wheel duty to 0 earlier, this could optimize turning radius
• increase outer wheel duty above configured duty limit (95)

tasks

• [x] test whether radius is not read 1 at low angles
  • wass issue due to wrong scaling
  • fixed in d715f2e0f1c82c65daf3b925532eddbb9e1ac62b
• [x] add threshold for joystick angle where the ratio snaps to 0
  • implemented in ffbf9ccec8574f791fef27001836568f5d1ed3f8
  • needs to be enabled later, see https://github.com/Jonny999999/armchair_fw/issues/19
  • now reworked and implemented in a6a630af44375add046985b84c615ead8bba3610
• [x] boost duty of outer tire https://github.com/Jonny999999/armchair_fw/issues/19 - added in a6a630af44375add046985b84c615ead8bba3610
• [ ] more responsive
  • see https://github.com/Jonny999999/armchair_fw/issues/21

Implemented BOOST of outer tire and snap to max ratio threshold in a6a630af44375add046985b84c615ead8bba3610 This, especially the boost, improved driving experience in turns significantly!
