switch to SnoopPrecompile.jl

[ranocha]

I basically followed the recipe of https://timholy.github.io/SnoopCompile.jl/dev/snoop_pc.

Not necessarily related to this PR: Do you know why we get so much compilation (and recompilation!) when using Octavian? With this branch on Julia v1.8.3, I get

   4687.4 ms  Octavian 88.09% compilation time (55% recompilation)

after everything has been precompiled. It seems to get better with Julia v1.9.0-beta2, so there is no need to dig too deep if there is no obvious answer for you.

This is Octavian.jl from this branch with CPUSummary v0.2.1 but on Julia v1.8.3

[ranocha]

Julia v1.9.0-beta2 yields
