ProtoPromise v3.0.0

[timcassell]

v3.0.0 has been released!

This major version update was mostly done to clean up the code, remove deprecated and useless APIs, drop support for ancient runtimes to make maintenance easier, and improve performance.

New async/await performance numbers in .Net 8 compared against other async libraries:

Type	Pending	Mean	Allocated	Survived
ProtoPromise	False	172.6 ns	-	-
Task	False	260.9 ns	192 B	-
UniTask	False	306.8 ns	-	-
UnityFxAsync	False	368.6 ns	360 B	-
ValueTask	False	337.4 ns	-	-
ProtoPromise	True	1,402.3 ns	-	648 B
Task	True	2,110.8 ns	1120 B	-
UniTask	True	1,817.7 ns	-	744 B
UnityFxAsync	True	1,998.2 ns	1952 B	-
ValueTask	True	2,486.9 ns	968 B	40 B

Full results

I can now confidently say that ProtoPromise is the most efficient async library in .Net!

(I haven't figured out how to run these benchmarks in Unity IL2CPP so far, unfortunately.)
