Feature request: support for instant-cast spells

My current build benefits from casting two spells at the same time.

With current behavior, the bot will stop casting my prio 1 main attack to cast the prio 2 “buff” attack, and then resume casting the prio 1 until 2 is off cooldown.

In manual play, I never need to stop casting the first attack.

Proposed solution is to add an “instant cast” field in combat skills ini
