Fixes #50. Avoids the OnceCell by making
ThreadIdManagerconst-initializable. This doesn't require a MSRV bump as aggressive as #64, as it only requires 1.63 to makeMutex::newconst. UnfortunatelyBinaryHeap::newis still not const, so this PR wraps the freelist in an Option to allow initializing it to zero. It should still be cheaper than the atomic check of aLazy, and this is only done when new threads are registered.
