alertable spaceman v2

slight modification to Key Levels SpacemanBTC IDWM script
credit: spacemanbtc

this is a new version to fix a bug that would pop unwanted alerts on certain levels. I realised the issue was how tradingview handles time. in tradingview,1D paints a new candle at 7pm NY time, but in low timeframe, the "next" day doesn't officially start until 12a.m, like a military clock would. this would cause some repainting issues.

implemented some changes by using stable values that would hopefully circumvent that. script is open sourced in case anyone wants to use it to make changes in case there are other issues
