Some small improvements

I've split up the generated haskell modules into even more files for faster builds on large projects. And added some strictness annotations to the logger

What is the benefit of that?

Should make it minimally faster. I initially worked on some larger refactorings of the logger to make possibly extract it out into it's own ihp-logger package. But that failed as it would break too much b.c., so that was the only commit I could use from that :)
