add a script to clean up db output and run it before build script

fixes #64 CC @SebastienGllmt

Is there a reason you put these in the db/package.json instead of the root package.json?

[GGAlanSmithee]

No, not really, I'm just used to localize the scripts to where they are ran, and it made more sense to have it there when the script was rm -rf tsconfig.tsbuildinfo & rm -rf build, but now, that we are using wipe.sh, it does make sense to run it from the root.

However, I would suggest to also run clean when running build, since that is where it is of most use, because if not, it will fail silently (fail as in not produce new output), which was the reason why I wanted to add this in the first place. And in this case, it is a bit awkward to have the clean script in the parent package.json and the build script in db/package.json.

I guess it boils down to if you expect users to run scripts directly from the db package, or always operate from the root.

it should never be required to run clean before build. If your code changes, it will automatically know to rebuild (that's what tsconfig.tsbuildinfo is for). Usually the only time typescript fails to detect changes are cases related to bumping dependencies that include special tools (which is why the wipe.sh command also wipes node_modules

ok, understood. In that case there is something else at play here, I would think. I need to investigate further.

@SebastienGllmt If you look at the changeset based on the last commit, I think things will look a bit more reasonable to you.
