Created the project
an eventstreammigrator reads the eventstream
moved eventstream migrator into its own project
the eventstream migrator gets migrations
migrating an event
saving the migrated events
changed the interface of the eventstreamreader
already behaves a bit in a stream kinda way
added tests
having the next migration pick up the migrations of the previous migration
outputs of previous migrations become inputs of next migrations
small refactor
added some failsave stuff
