:art: :fire: Customizable accident speed damage

[ArturMichalak]

Hi community

Describe Pull request I want to have more control over the characters ejection, so I added some parameters to the configuration. Moreover I rewrote speed damage control section, hoping it would be more readable without negative impact on performance. By the way, the linter showed me that subtraction assignment doesn't work in lua, so i changed it. What does it actually look like?

Questions (please complete the following information):

• Have you personally loaded this code into an updated qbcore project and checked all it's functionality? Local instance only. It would still be worth testing.
• Does your code fit the style guidelines? I tried to fit
• Does your PR fit the contribution guidelines? I hope so
