perf: using dirty bool instead of index

[James-Frowen]

Sends 1 bit for each component instead of 8 bits per dirty components.

This still in draft state? What was the whole plan and initial design around this. The more we squeeze performance or squeeze down the bytes during spawn / sending messages the better. So did this not pan out?

[James-Frowen]

This was just a rough idea to try it out, I think it works.

One of the downsides is that it is not always less bytes. if you have 9 components, but only 1 of them changes, you'll now be sending 9 bits, instead of 8 bits (the index as byte).

The Optimal way would be to send a bool to say if the message is using index or mask. but this level of optimization might not be worth it because it'll only be saving bits.

Once I start optimizing my game projects I'll be able to test this changes to see how much of a difference they make for real.
