[Request] Ninja - Burst Cooldowns

[Elefay]

Describe the feature you'd like

I'd like to implement a few features relating to ninja's burst cooldowns.

This is a general outline:

1. Mug / Dokumori > Ten Chi Jin > Meisui > Tenri Jindo
2. Kassatsu > Trick Attack / Kunai's Bane > Assassinate / Dream Within a Dream
3. Bunshin > Bhavacakra / Hellfrog Medium
4. Phantom Kamaitachi > Throwing Dagger

#​1 and #​2 combine our six one- and two-minute cooldowns into two, freeing up four buttons. In contrast with #​1 below, #​2 also lets you get the cooldown rolling on Kassatsu sooner and potentially squeeze another action into Trick Attack / Kunai's Bane. #​3 prevents you from severely drifting Bunshin by accidentally using Bhavacakra / Hellfrog Medium while also freeing up another button. #​4 is an extension of #​3, but it also stands on its own since we typically prefer Phantom Kamaitachi to Throwing Dagger for uptime.

Ten Chi Jin > Meisui > Tenri Jindo already exists, so #​1 could just be Mug / Dokumori > Ten Chi Jin (implemented in a way that's compatible). #​2 and #​3 could likewise be broken down into multiple features. #​3 would also have to be compatible with #​4 below. #​1 and #​2 would be mutually exclusive with #​3 and #​1 below.

Describe alternatives you've considered

The following features currently exist:

1. Trick Attack / Kunai's Bane > Kassatsu
2. Ten Chi Jin > Meisui > Tenri Jindo
3. Hide > Mug / Dokumori
4. Bhavacakra > Hellfrog Medium

These work fine, and I currently use all except #​4. The only one I have an issue with is #​1 (as noted above). That said, the above changes would free up two more buttons and feel more streamlined.

Additional context

Edit 3/29: It might make more sense for Phantom Kamaitachi to replace Death Blossom / Hakke Mujinsatsu. Ninjutsu would take priority if that option is enabled.
