The package with the main function should always have the name main. This was not the case in three packages. This was silently allowed before, but since a TinyGo change (https://github.com/tinygo-org/tinygo/pull/1592) this now results in a linker failure. Perhaps this should result in a better error message in TinyGo. However, the example code also needs to be fixed, so hence this PR.
