Feature/44 read write historic slots (#46)

Browse Source 
* Update boot to set processing type.

* Handle entries from the historic_process table.

* Update on-pr.yml

* Fix head processing Error

* Update names and debug

* Seperate checking for new entries and locking them

* Application can process historic and known gaps

Untested

* Handle genesis

* Update remove entry for knownGaps, viper

* Disregard unused code from linter
