Switch from PackageCompiler to JuliaC

[SouthEndMusic]

@visr has been looking into using Julia 1.12 for Ribasim. It turns out that at the time of writing there are some issues to resolve with this new Julia version, so we should wait until these are resolved before converting.

There are several 1.12 features that will be beneficial to Wflow:

• Workspaces: these allow for sharing a single manifest between multiple projects/environments
• Building binaries with JuliaC.jl, which allows for shorter building times (and building smaller binaries with fully type stable code, which Wflow.jl is not at the moment)
• Revising structs: With this you don't have to restart your Julia session when changing structs during development

@visr can we close this issue?

No, the second bullet still needs to be addressed, similar to Deltares/Ribasim#2761.
But indeed we are on Julia 1.12, so I renamed the issue.
