UnitAura states, auraInstanceID update

[httpsx]

• Fix custom size buffs
• New api UnitAura (usePackedAura)
• Update buffs / debuffs with auraInstanceID state (10.0 update)

Auras now have an "instance ID" (auraInstanceID) which uniquely refers to an instance of an aura for the duration of its lifetime on a unit. The instance ID is expected to remain stable and suitable for use as a table key between successive updates of auras on a unit until a full aura update occurs.

The old version causes errors because the tooltip now requires an auraInstanceID ( C_TooltipInfo.GetUnitBuffByAuraInstanceID )

• Fix cache frame colors

Some frames after joined a group could be displayed as "disconnected"

frame.healthBar always {0,1,0}
You can get current color with frame:GetStatusBarColor()
