make unit test run un-slow again.

[CyonAlexRDX]

Note

Target branch is not main, rather Ghenadies UniFFI branch
We really want this change on main too, but we expect to merge the UniFFI sep branch soon

Make unit test run in 80% faster (On my Mac Studio, now rung in 40s instead of 75 sec).

The slow test run in 1.3 sec instead of 5.3 sec.

The culprit was the manual look up in sample_associated_mnemonic using if == comparision, instead of using a map structure.

I profiled using flamegraph which is a great tool. It is a bit hard at first to understand. It is the width of the rows which matter, not the color nor does any horizintal position matter.

See flramegraph file - this is run before this optimization

You need to boot your mac in Recovery Mode and disable SIP for dtrace to get flamegraph to work - follow this answer if you wanna try it yourself: https://stackoverflow.com/a/33584192
