Custom Sessions with Mitigation Logic

This script is for people to mark their choice of time ranges where the high and lows get extended until mitigated. There is logic involved to make the charting process and the clean up a whole lot easier.

This includes:
- 5 Custom sessions
- Custom colours
- Custom labels
- Custom time zone (for easier use)
- Auto extended lines with mitigation logic

Mitigation logic:
The highs and lows will be extended until mitigated where they will then be turned to a dotted line until the end of the day which mitigates it.
If the sessions high/low gets mitigated on the same day, it will still change to a dotted line and will stop at the end of the day.
