Add presence penalty (openAi/ollama/others) and repeat penalty (ollama only?)

- Add Presence Penalty, which I believe most providers have.
- Add repeat_penalty, an Ollama / Llama.cpp only parameter
- Widen temperature range to 2 (supported by many providers and similar front ends)
- Widen Top K range (supported by many providers and similar front ends)
- Adjust description of freqency_penalty in line with OpenAI documentation
- Add presence_penalty with an OpenAI documentation based description
- Add repeat_penalty with an Ollama documentation based description
