v1.4.20 (#244)

Browse Source 
* v1.4.20 base

* add inmemory dev mock for hypergraph

* add simple rdf + tr

* Update config.go (#234)

2 of bootstrap nodes are going to be closed due to low performances. Will consider to replace with better specs.

* go mod tidy

* go mod tidy

* bump name in readme
