Migrate SnoopPrecompile.jl to PrecompileTools.jl

[JordiBolibar]

Investigate the use of SnoopPrecompile.jl for the ODINN.jl package. So far I have already implemented it in the #invert branch, but I still haven't properly assessed if there is any benefit in terms of performance. I should also check more in detail how to correctly use, since it was just a quick test.

I have already implemented a first version of SnoopPrecompile.jl, but it's very hard to tell if it's actually improving anything. We should take a closer look at this, and perhaps @facusapienza21 you could be helpful here, now that you have a better understanding of precompilation.

This package is now deprecated. To be migrated to PrecompileTools.jl: https://julialang.github.io/PrecompileTools.jl/stable/
