✨ Implement individual Configurable HyperOptable Weighted Signal Cross values

[Rikj000]

It could potentially be beneficial to make weighted signal cross values HyperOptable too.

For example with the current implementation:

• RSI cross for buy happens at a static 30
• RSI cross for sell happens at a static 70

I think it can have some benefits to make that 30 & 70 HyperOptable as well.

For example:

• Search for an RSI cross for buy between 25 - 35
• Search for an RSI cross for sell between 65 - 75

Of course we'd have to be careful, it might as well make the search space too big 🤔
